Best ResponseYou've already chosen the best response.0y 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.

Best ResponseYou've already chosen the best response.0y=kx => k = y/x = 68/5, for x=6 => y=68 *6 /5 = 81.6

Best ResponseYou've already chosen the best response.0try to do it, it's so easy.. just substitute y=68, and x=6 in the equation y=kx.. and solve for k.
