Question

Help! Thank you in advance!

Answer 1

C

Explanation:

-3x + y = -7

use (3, 2) as plug ins for x and y

-3x + y = -7 (rewrite)

-3 x 3 + 2 = -7 (solve)

-3 x 3 = -9

-9 + 2 = -7

same with the other numbers (2, -1)

but i'm lazy

Answer 2

option 3

both (3, 2) and (2, -1) are solutions
