y = -3x + 7

Step-by-step explanation:

We are given that the slope of the line is -3; this means that m = -3.

So, y = -3x + b.

Now we need to find the y-intercept, or b. To do this, we substitute the given point (5, -8) into this function y = -3x + b.

It will look like this:

-8 = -3(5) + b

Simplify and solve for b.

-8 = -15 + b

7 = b

Now that we know what the y-intercept, or b, is, we can put this value back into our equation to get y = -3x + 7.
