1) Find Slope %28y2-y1%29%2F%28x2-x1%29
%288-0%29%2F%280%2B5%29=8%2F5
2) Flip the Slope then add a Negative Sign
%288%2F5%29 Flipped %28-5%2F8%29
3)y=mx+b Plug in %28-5%2F8%29 for m
y=%28-5%2F8%29x
4) If you need the equation to plug into a point then just substitute x and y in the equation to find b. b is also where the line touches the y axis.
