# Maths Question? watch

1. (Original post by Dinaa)
I think OP is talking about the change in y would be 0 and the change in x= a constant

therefore change in y/change in x= constant/0
Is that meant to be in that order? (you said change in y=0, but then in the equation put it as a constant?)

I actually meant that if x=3, then y values are changing but x aren't, and thus dy/dx is a constant divided by 0.

But don't worry now, I understand!
