(8, -29)


(8, -64)


(8, 19)

Answer 1

just plug in the given values of x and y from each option into the equation and see which ones fit.

Answer 2

Alright so a ordered pair is when you can take out x and y and put in there values, and then the equation = to true.

Lets try A:
-3x + y = -5
Replace
-3*8 + -16 = -5
~False, so not A.

Lets try B:
-3x + y = -5
Replace:
-3*8 + -29 = -5
~False, so not B.

Lets try C:
-3x + y = -5
Replace:
-3*8 + -64 = -5
~False, so not C.

Leaving us with D, but lets check:
D:
-3x + y = -5
Replace:
-3*8 + 19 = -5
~True!

Your final answer is D.
