Assuming that

is the amount of hours spent doing homework:
Plug in

for


,

That means that since a

value is the test score (because that's what the y-axis is labeled), your predicted test score is a
64.
H-5 = -30
Add 5 to both sides to get variable h by itself
h = -25
R=21. 21/3=7. To check your answer, you can do 7x3 and it'll equal 21.
