The equation would be y = 3x
Step-by-step explanation:
The slope intercept form is y =mx +b
You start at the middle point and count up 3 until you’re on the same line as the other point and then you count over 1. That is your slope, your mx. Which is 3x (because the 1 doesn’t need to be shown) and the b is 0 meaning the point that is on the Y line. You start at 0 so you don’t need to put that in.
