Answer:

A

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.

y = -5x - 4

Test:

-52 = -5(10) - 4

-52 = -54 FALSE

-39 = -5(7) - 4

-39 = -39 TRUE

31 = -5(-7) - 4

31 = 31 TRUE

-44 = -5(8) - 4

-44 = -44 TRUE
