    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.
