  1. Make y the subject of the equation
    y = -4 - 6x


    2. Substitute values for guess and check
    8 = -4 - (6 x 2)
    8 = -4 - 12
    This is incorrect.

    2 = -4 - (6 x 1)
    2 = -4 -6
    This is incorrect.

    -10 = -4 - (6 x 1)
    -10 = -4 -6
    This is correct.

    The correct answer is C.
