number 7 which graph represents the equation 5 y - 3x equals -15 do this a couple different ways I think on the earlier video I did it like this one thing you do when the numbers are pretty easy and you can see the you know factors of each other or what not then you know you just want the X and Y intercepts and the x intercept is where 0.2 x intercept x intercept will be where the Y is 0 so far clothing 04 why accidents that would be -3 times what number is -15 that makes the x-intercept 5 that means this line crosses that over five of zero as this one does and as this one does being see cross at 5 D does not in a does not so we're first Corners X7 Corners why the x-intercept is where why was 0 and Y equals 0 we plug in 04 what right here to goes away -3 * 5 is negative so this line crosses at x equals 5 so he could be either this one or if you need to be or sit on The Wire can see if there's any Clarity the y intercept at the Y intercept the x coordinate is 0 x 0 at the Y Corner sofa plug-in 0 4 x right here negative zero goes away and then all I have left is 5 times what number is -15 will that will have to be negative three so this one very limited and right so those can go away I need a line that crosses at or 0 down a of 3 is my wife is here at / 0 name 3x + 7/5 of 0 kiss meme be as the correct Choice using the intercepts method of doing this the other students I prefer to put this in slope intercept form and grabbing baby so this is in Lawless not even any kind of form I guess we can go ahead and put this thing in y intercept form when we get the Y by itself  so we're getting 5y - 3x equal -15 I won't lie about self so the first thing I'm going to do is I'm going to add 3 extra bull size my text tone on the other side  this goes away I bring down 5y  no earlier do you know a lot of asthma one revolves around y equals MX plus b so encourage students to go ahead and write the MX term which would be reacts first so right there here and then the bean wines that would be at this point just a constant is -50 but we still don't have why about self cuz I was being multiplied by 5 so rid of that x 5 coffee in the volume of 5 and if we divide this cyber five we divide all of this by 5 one day lineup  how's it going to do it individually cuz some students need to see it done both for divided this I have a 5 or divide everything else on this 55051 once I was white as why and why is by itself now that I have is I have a slope that go fishing turn off 3/5 Rise 3 Run 5 rise over run through a 5 and -15 divided by 5 Dance 3 so subsist prefer to look at it in the slope intercept form of the line so you need a wine at starts on -3 + it's awkward because this is a positive slope it's Landing awkward and that automatically eliminates d d and c or playing downward so it can't be either of those can't be seat or the exhaust now and then I need one that starts on Siri and obviously B starts on -3 and it looks like it rises 312 it runs one two three four five six three one two three Migos Up 3 comes over 5 1 2 3 4 5 so rise of 3 and a run of five one two three one two three four five rise of three five there again be selection and whichever method works best for you is the method you use
