Sphinxa [80]

Hey there! :)

Answer:

C. Both (2,1) and (4,9)

Step-by-step explanation:

To solve this question, simply plug in the coordinates of answer choices given into y = 4x - 7:

A.

1 = 4(2) - 7

1 = 8 - 7

1 = 1. A is correct.

B.

9 = 4(4) - 7

9 = 16 - 7

9 = 9. B is correct.

Therefore, the correct answer is C. Both (2,1) and (4,9) are solutions to this equation.
