Find the slope using the two points.
m=%28y2-y1%29%2F%28x2-x1%29=%28-4-5%29%2F%284-%28-2%29%29=%28-9%29%2F%286%29=-3%2F2
Now us the point-slope form of a line with either point, y-yp=m%28x-xp%29
y-5=-%283%2F2%29%28x-%28-2%29%29
y-5=-%283%2F2%29%28x%2B2%29
y-5=-%283%2F2%29x-3
highlight%28y=-%283%2F2%29x%2B2%29
