r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

$8=\frac{4}{3}(-4)+b$

After solving the equation, b will equal -16/3 making the final equation be

$y=\frac{4}{3} x-\frac{16}{3}$

Using the equation, you can solve for r.

$12=\frac{4}{3} x-\frac{16}{3}$

This will bring the answer being r = 13
