Easier to use point-slope form, and transform the equation into standard form.

y-v=m%28x-u%29, generalized point-slope form, using point (u,v).
m=slope, vertical change divided by horizontal change.

m=cross%28%283-%28-5%29%29%2F%28-1-%28-2%29%29=-2%2F1=-2%29,was a mistake;
m=%283-%28-5%29%29%2F%28-1-%28-2%29%29=%283%2B5%29%2F%28-1%2B2%29=8%2F1=8
Next, pick either given point;
y-3=8%28x-%28-1%29%29, now corrected;
You can finish putting this into the standard form.


(Try to look past my earlier mistake, and transform the point-slope form into standard form.)
