Best ResponseYou've already chosen the best response.1So, all I did was basically the same thing, but the only twist here is that I flipped the "x" and "y". See that?

Best ResponseYou've already chosen the best response.1So, with these "varying directly" problems, you can start out the same way in both cases. Nice working with you!
