today we're going to rip your massive review on the always-on have class so just give me a Nike video but I think it's going to help you not just this year but for sure I just want to get you into algebraic Concepts in 7th grade 8th grade for the end you will see see more of the questions and for sure and I'll give her one but everything that I am going to review with you instead of just giving you work shoes or just singular concept I want to present it the way that you're going to start seeing it before so this is your bored with it all ready for you I am going to create a right triangle if I create a right triangle and I'm just going to put a. D r a. right I'm going to connect the three dots to make my right triangle when I do that I get yeah yeah we know it's a right triangle because as a 90° angle and what our goal is is the find the equation for this title line and when we talk about online with a right triangle is called the hypotenuse in Tights and you will use Pythagorean theorem to find the length of the hypotenuse and I want to tell her that aspect of it even though it's free straight forward with exponents but I am strictly going to talk about the hypotenuse and the equation of this linear equation linear means a line of an equation I am by Lakeland a B & C just identify the time that's you remember how to write this using your triangle symbol a a y a b c a b c 180 Diane Highway connected all the way across 360 my ordered pairs my coordinates is 1 - 1, 3 BS -1, - 2 negative write -1, - 20 right and what is the value of C of my order or I mean - 2 looking at that hypotenuse on the diagonal of my right triangle what are the two ordered pairs that I must use so I'm going to use from here all the way to here don't worry about I'll be there right now here is the first thing you are going to do you are going to lay more eggs 1, X 2 what have my order. If I label it can I label as X1 next to I mean thank you somebody catch me we are human we cannot not make mistake all right so now I can't see have the same labeling of X1 y1 add subscription to, ask you again now why such a steep a line is and if you think of climbing up with one's going to be okay so we are looking at the house Steve this line is give me lot easier to climb then finding something like this so this is why we are going to find the smoke with the letter M please don't ask why you being my slow Biz appointment has the letter M I don't know be honest with you but it's just so why chairman has wise up script one over at subscribe to my subscript one yeah now we're going to be reviewing all I need iLearn and before we go into this you are going to learn or review integer rules crashing rules variables substitution distributive using linear equation my hip to you I would write this when when given a formula or equation when given a formula or equation I'll be riding you'll be able to use these nuts when you get into middle school high school when given a formula an equation that has a negative or a minus and the substituted the substituted by you is a negative and I will model this for you and the substituted IU is a negative please put it in Peru disease yes big please please put it in the parentheses to protect - within the equation formula I'm saying and minus cuz I see a minus symbol in my formula right here I thought those were done. Minus symbol minus symbol minus do better yes I'm dead all right let's see if this works all right we have to find a slope and I can already tell what the slope is but we'll go from there but based on my picture looking at the hypotenuse of line segment AC can you tell me right now is that a positive slope or negative slope and I and why you said what you said - Beyonce's - alright the gas in passes through your corn I mean your quadrant through negative quadrants which is the negative one of each man and it reaches my quadrant number for which is a positive negative the one of each is going to give you I measure the positive positive negative negative if I were connected as going to deposit slip number this Amadeus you can call this guy at home and we use our tic-tac-toe for integers a multiplying dividing with integers so this is what we are going to refer to and relating integers with coordinate plane what we're doing here I'm going to now what is the value of my Y2 -2 - 2 parentheses - what is my why 13 or minus what is 1 - one put in parentheses oh I see something to eat so what is a negative 2 - 3 linear feet again I like to think of a number line I'm going to start at -2 Midas Sprint if you have to close your eyes minus on a number line - When you subtract the move to the right or to the left -2 and I move over to the left how many three times where will I end up what kind of 5 - -3 every year I mean R X Plus and a minus what kind of tree is this do you understand that Jonathan yes I don't know who's who it is because I'm far away from my monitor so now so I add up my negatives which is a 5 and I spoke to my native symbol so therefore is a -5 is the value of my addition of my numerators now what do I see if my denominator - + - + - we have back-to-back negative and positive because we are a team negative times a negative which is a what that takes care of this so I just rewrite the numbers for the front and A1 so now I get - 5/5 + what is -5 / 50 tell me why you believe it's a zero Mister Parker you got to start over 5 is it's not zero tell me what it should be been Mister Parker 311 what kind of wine is it though appositive or appositive explain to me a negative sorry okay I'm really confused pressure is a negative because a negative and a positive and negative I'm trying to figure out how she got to know you do - what - 5000 + 5 - 1 okay can you say correctly what what math divided by 5 is -1 thank you again knowing that this is a negative in the numerator and a positive and the denominator negative divided by a positive Midnight Madness 5 divided by 5 which is one this is our fraction rules so therefore m-my slope 1 what does that mean negative thank you it means that I can start an A or B and can again rise over run rise over run so if I start here I have to go up one over to the left one because it's a negative so I can see this pattern develop 1/1 up 1/1 up 1 / 1/2 1/1 is how you understand the actual slope of this particular triangle. and if I wanted to I could have gone from a rise over run well it's the opposite since I'm going downstairs down one different color down one over 1,000 110 down over down or down over the biggest that it creates the stair step what's your question Arby's number so meaning of numbers on your example and I will work with you after this one now the next thing you'll be doing you are going and then right over here no Y intercept form using a or b a c I don't care which one so on your homework you got to pick out which one you want okay I'm just hearing you say using a and what is my order pay for a either one, three find the slope in her step using a which is -1, 3 find the slope intercept of this lie I'm going to give you a hint if you are ever given a picture and it's on a coordinate the fancy way of do y intercept memes where V Line crosses the Y access where does it cross the y-axis only two that I know of y intercept which is symbolized by the letter b is 2 well you see how we use the KU goes why over and I why you don't stay at correct Bad Dad hey the K is your coefficient which really becomes yours slope all right so we are okay is to now I'm going to show you why this works are you ready why is equal to mx + b what was the value of my why 33 this is your ex right here and this is your why 3 equals what was the value of M -1 - 1 parentheses what is the value of a - 11 + b what is what is it that we need to simplify - 1 + - 1 so what is a negative times a negative you need to talk or you have on the same side as my be variable what kind of one possible positive negative come on this side beagle you have to just wait till 3 B&D coaches to and it's not what I said it was going to be just baby a lot of work well once you see a crossing over yes now am I done now I have to put into my scope intercept form so why is it go to Waze my slow 2 -1 - 1 but X what was my b or why is equal to negative plus two that's my final answer. so that far -1 * X is negative X so now I'm just going to use my fingers late the Y a bright on my line Y equals negative X Plus is my equation my linear equation for my hypotenuse connecting a and C this is a slope intercept form and what's I recall was a here's a project that I got from my former students 390 this is exactly what we just did and this was he's in he's a sophomore now so he's taking right now he's taking Advanced geometry and when he was in Algebra 1 in 9th grade this was his project that he did and got it back and then you friend Ben gets me so you can all the different lines and yet to find the equation of those lines for all of these lines on here and that's what I just showed you I just did it with a right triangle that's just one you can see how much he had to show back so therefore was there anything that we just did on the board that I did not cover the school year no Google isolation of Concepts and I could have made this an inequality if I wanted you then all you have to do is either shade on the bottom side of the equation or the top side of the equation with an e quality line or a solid line so what I'm trying to do is I'm preparing you for all of your middle school expectations and tell me the you will be able to take advanced math next year as a 7th grader then so you'll take three hours for the next year depending on what their qualifications are in 8th grade you will be able to take Algebra 1 as a eighth grader and you're not the way it tells ninth grade so you can then we get the nice place to go straight to Geometry song do I have that ability to do that and that's what I'm trying to prepare you again this problem itself all the things that you see we've covered one by one little pieces at a time going to school yet now my job is to extend and show you how the things you learned is going to be transferred for 7th grade and 8th grade and you can do that all right stop stop recording what is the best rated
