Answer:

(-6,2)

Step-by-step explanation:

An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.

-3x - 7y = 4

Substitute:

-3(-5) - 7(2) = 4

15 - 14 = 4

1 = 4 FALSE

-3(2) - 7(-5) = 4

-6 + 35 = 4

29 = 4 FALSE

-3(2) - 7(-6) = 4

-6 + 42 = 4

36 = 4 FALSE

-3(-6) - 7(2) = 4

18 - 14 = 4

4 = 4 TRUE
