The answer is -30.

1. Plug in the points into the formula. m=y2-y1/x2-x1

2. Simplify

3. Multiply both sides by 4, you will get r-2=-32

4. Solve for r

5. You can double check to see if you got the same slope

Done!

Find the value of r so that the line passes through (1,2) and (5,r) has a slope of -8
