Determine which ordered pair is not a solution of y=-5x-4 a. (10,-52) b. (7,-39) c. (-7,31) d (8,-44)

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
