You can put this solution on YOUR website!
h%28-4%29=%28-4%29%5E3%2B5=-64%2B5=-59
h%28-2%29=%28-2%29%5E3%2B5=-8%2B5=-3
So now calculate the slope of the line,
m=%28-59-%28-3%29%29%2F%28-4-%28-2%29%29=%28-56%29%2F%28-2%29=28
Use the point slope form with either point,
y-%28-59%29=28%28x-%28-4%29%29
y%2B59=28%28x%2B4%29
y%2B59=28x%2B112
y=28x%2B53
