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.
