    The inverse function is (x-7) / 9

    Step-by-step explanation:

    y = 9x+7

    Exchange the x and y

    x = 9y+7

    solve for y

    Subtract 7 from each side

    x-7 = 9y+7-7

    x-7 = 9y

    Divide each side by 9

    (x-7) / 9 = 9y/9

    (x-7) / 9 = y

    The inverse function is (x-7) / 9
