    The inverse is 9/10 (x-11)

    Step-by-step explanation:

    y = 10/9x + 11

    Exchange x and y

    x = 10/9 y + 11

    Solve for y

    x-11 = 10/9 y+11-11

    x-11 = 10/9y

    Multiply each side by 9/10

    9/10 (x-11) = 9/10 (10/9) y

    9/10 (x-11) = y

    The inverse is 9/10 (x-11)
