Anyone good at economics?

This will sound sort of lame but I'm pretty stuck on my economics homework and I was hoping someone could help me.

There are like a dozen problems I can't get, but basically I'm not understanding how to graph iso-revenue lines, and not sure how to calculate supply and demand curves—because my graphing calculator is giving me negative results for the supply curve, and I don't see how that could be right (or how to derive an equation from a table of prices, quantities demanded, and quantities supplied).

Any help would be supremely appreciated.
