m=slope
%28y1-y2%29%2F%28x1-x2%29=m find slope formula
%287-4%29%2F%283-7%29=m imput points and solve
3%2F-4=m multiplied by (-1/-1) which=1
-3%2F4=m
y=mx%2Bb slope intercept formula
y=%28-3%2F4%29x%2Bb imput one point and solve for b
7=%28-3%2F4%293%2Bb
7=%28-9%2F4%29%2Bb
7%2B%289%2F4%29=b
37%2F4=b
y=%28-3%2F4%29x%2B%2837%2F4%29 heres your equation
