    Step-by-step explanation:

    y = kx, where k is a real constant.

    When x = 8, y = 24.

    => (24) = k(8), k = 3

    Therefore when x = 5,

    y = kx = (3)(5) = 15.

    Answer:

    y=15

    Step-by-step explanation:

    you do 24/8=3 and  that lets you know that y is 3 times the x value. (8 x 3=24). So then just multiply 5 by 3 to get 15.
