All right, and this one, they give you a slope and a point, and then they ask you to determine which of the three sets of points also lie on that same line.
00:12
So i do need a slope intercept equation, as that would be the easiest.
00:17
I can just plug in and see if that equals any one of the numbers, and i can quickly check.
00:23
So point slope form is y minus y1 equals m times x minus x1.
00:29
So it's y minus negative three equals five -fourths x minus two.
00:39
Okay, so it's y plus three equals five -fourths x minus, um, what is that, five -haves? five -haves.
00:52
So if i subtract three, so i should get y equals five -fourths, x, um, was it six? so minus 6, it would be minus 11 over 2...
