Question

which ordered pair is a solution of the equation y=4x-7 A. only (2,1) B. only (4,9) C. Both (2,1) and ( 4,9) D Neither

Answer 1

Hey there! :)

Answer:

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

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.
