Variation statements translate as follows:
. . . . ."y varies directly as x": y = kx
. . . . ."y varies inversely as x": y = k/x
. . . . ."y varies jointly as x and z": y = kxz
Translate your exercise into the appropriate form. Plug in the given initial values (x = 3 and y = 8) and solve for the value of k. Then write out the variation equation.
