    Answer:

    f(x)=-3x+4

    (can’t see some of your choices)

    Step-by-step explanation:

    We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y’s value will depend on our choosing of x.

    So we need to solve for y.

    9x+3y=12

    Subtract 9x on both sides

         3y=-9x+12

    Divide both sides by 3:

         y=-3x+4

    Replace y with f(x).

        f(x)=-3x+4
