    The answer is D) Y = 3/4x-2

    3x - 4y = 8

    Express it in the term of y.

    Subtract 3x from both sides:

    3x - 4y - 3x = 8 - 3x

    - 4y = 8 - 3x

    Divide both sides by - 4

    -4y/-4 = (8 - 3x) - 4

    y = 8/-4 - 3x/-4

    y = - 2 - (-3/4x)

    y = - 2 + 3/4x

    y = 3/4x - 2
