6 0

The correct answer is a.

You can find this by using each of the ordered pairs in the equation and seeing if the statements are true. The work for the a ordered pairs is below.

(-2, -14)
y = 7x
-14 = 7(-2)
-14 = -14

(3, 21)
y = 7x
21 = 7(3)
21 = 21

(-4, -28)
y = 7x
-28 = 7(-4)
-28 = -28

setting it up looks like this

tan 72° = $\frac{x}{8\\}$

solving for x gives us x= 8×tan 72°

which is about 24.62
