    y is directly proportional to x means that: y=kx for some real number k, to find the value of k, just use the info that y=-68 when x=5.

    y=kx => k = y/x = -68/5, for x=6 => y=-68 *6 /5 = 81.6

    try to do it, it's so easy.. just substitute y=-68, and x=6 in the equation y=kx.. and solve for k.
