Hello everyone! Its me! I'm stuck, these are suppose to be exact equations, and yet its not in exact equation forum. I thought being an exact equation you have to have the following form:

But my question is the following:
Find a function F(x,y) whose level curves are solutions to the differential equation

I rearranged it so its now:
y - x dx/dy = 0
but its not dy/dx, its dx/dy! so what happens? T hanks.
