Find three solutions of the equation. y = 7x a. (–2, –14), (3, 21), (–4, –28) b. (0, 0), (–3, –23), (–2, –14) c. (3, 21), (0, 0), (–1, –6) d. (–2, –14), (3, 21), (2, 13)

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

C

Step-by-step explanation:

The answer is C because both of the equations have less than or equal to symbols. So, you would shade below both lines. The only place where the two lines mix shades is C.
