Odd question. If you mean that in both cases y is a function of x, then the first case is a straight line (for constant a), and the second one is a Sqrt type curve plus a linear component. Plot both with different arbitrary values of a, b and c. I see no relationship whatsoever, save for the fact that both share(presumably) the same constant a. Perhaps you'd care to explain what is your problem?
