Answer:

y=-3x-4

Step-by-step explanation:

First, put the equation in point-slope form.

Remember, point-slope form is this: y-y1=x(x-x1)

When you put the numbers in this form, you will have: y-8=-3(x+4).

With the equation in point-slope form, you can now simplify that to get:

y-8=-3x-12

Now, move the -8 to the right side of the equation and combine like terms.

y=-3x-4
