Answer:

C. (5,1)

Step-by-step explanation: You have to substitute the numbers in for x & y

A. (-4,1):

2x − y = 9

2(-4) - 1 = 9

-8 - 1

-9 = 9

NO


B. (-2,5):

2x − y = 9

2(-2) - 5 = 9

- 4 - 5 = 9

-9 = 9

NO


C. (5,1):

2x − y = 9

2(5) - 1 = 9

10 - 1 = 9

9 = 9

YES


D. (6,-3):

2x − y = 9

2(6) - - 3 = 9

12 - - 3 = 9

12 + 3 = 9

15 = 9

NO


Hope this helps you!!! :)
