    C.

    Step-by-step explanation:

    We need to write an equation in slope intercept form.

    x - 3y = 12

    - 3y = - x + 12

    y = 1/3 x + 12

    Slope = 1/3, so for perpendicular line slope should be - 3.

    A. x + 3y = 9

    3y = - x + 9

    y = - 1/3 + 3 slope = - 1/3

    B. 3x - y = 5

    y = 3x - 5, slope = 3

    C. 3x + y = 6

    y = - 3x + 6, slope = - 3

    D. x - 3y = - 3

    - 3y = - x - 3

    y = 1/3 x + 1, slope = 1/3
