Supply and demand question?

Question

What would the long-run supply and demand curves look like for the following:

At a given instant in time, with normal supply and demand curves, each supplier at equilibrium is about to become a demander for the equilibrium price.

An example: if the equilibrium price is $5 with a quantity of 10 (with 10 different suppliers), each of the 10 suppliers is willing to become a demander for a price of $5.

Answer 1

The supply and demand curves could have lots of different slopes -- steep or not. All we know if that there is an equilibrium in the market at Q=10 and P=5.

Answer 2

It would look like an X on the page.
