¤ As price falls quantity demanded rises
¤ As price rises quantity demanded falls
Rules for drawing a demand curve:

iii) to find the quantity demanded at any given price:

b) draw a dotted line towards the demand curve
c) draw a dotted line down towards the x axis

demand curve
¥ If the change in demand is caused by a change in
any other factor this is caused by a shift in the
demand curve
