    f (x) = - 3x + 4

    Step-by-step explanation:

    Given

    9x + 3y = 12

    We require to rearrange expressing y in terms of x

    Subtract 9x from both sides

    3y = - 9x + 12 (divide all terms by 3)

    y = - 3x + 4

    Expressed in functional notation by replacing y by f (x), that is

    f (x) = - 3x + 4
