Find three solutions of the equation.

1 answer:

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
