Understand that a demand curve shows the relationship between the price of a good and the quantity demanded, holding other factors constant.
Recognize that a movement along the demand curve occurs when the price of the good itself changes, causing quantity demanded to change but not shifting the curve.
Identify that a shift in the demand curve means a change in demand at every price level, caused by factors other than the good's own price, such as consumer income, tastes, prices of related goods, etc.
Recall that for a normal good, an increase in consumer income leads to an increase in demand, shifting the demand curve to the right.
Note that changes in the good's own price cause movements along the curve, and changes in supply affect the supply curve, not the demand curve.
