Which ones have x and y that move together without any other sort of interference?

I'll give you "B".  See how there is no additive part.  No variable in a denominator.

You find the other one.  It will take a tiny bit of algebra.

thank you for B but idk how to do this at all! @tkhunny

It is time to learn.  Solve for y in each case.  See if you have a constant term left over or if any variable ends up in a denominator.

Why have you been given this assignment if you have no chance to solve it?  It makes little sense.
