Ok, so I looked at the ones I got wrong, and I could not figure out or find the answers to 32, 42, 46, or 49. Could you help me out with those ones? --[[User:TrishaM|TrishaM]] 15:28, 17 February 2010 (EST)

:32: P is on the vertical axis, and Q is on the horizontal axis.  If the good is extremely (or perfectly) elastic, then a small change in price causes a huge in Q.  That must be a horizontal line.  Similarly, imagine a perfectly inelastic good:  it doesn't matter what the price is, the Q is the same.  That's a vertical line.
