A) (–8, 8)
B) (–6, 2)
C) (–2, 4)
D) (0, –4)
E) (2, –12)

Answer 1

Simple...

you have: y=-2x-8

Simply plug in the coordinates-->>

A.) (-8,8)

8= -2(-8)-8

8=16-8

8=8 (Yes/True)

B.) (-6,2)

2=-2(-6)-8

2=12-8

2=4 (No)

C.) (-2,4)

4=-2(-2)-8

4=4-8

4=-4 (No)

D.) (0,-4)

-4=-2(0)-8

-4=0-8

-4=-8 (No)

E.) (2,-12)

-12=-2(2)-8

-12=-4-8

-12=-12 (Yes/True)

Thus, your answer.
