Question two in assignment two says: "Suppose the price demand curve is P=$20-Q, where P is price and Q is quantity. Also suppose the price supply curve is P=$4+Q. At what price and quantity will the good be sold?" The lecture does not address how to work with these equations. Are we supposed to graph them using the price as the slope and Q as the y intercept? ~ [[User:SharonS|SharonS]] 17:55, 16 February 2007 (EST)
