Understand that a demand curve shifts when factors other than the good's own price change, such as income, prices of related goods, tastes, or expectations.
Recall that for a normal good, an increase in consumer income leads to an increase in demand, shifting the demand curve to the right.
Recognize that a decrease in consumer income would decrease demand for a normal good, shifting the demand curve to the left, so this does not increase demand.
Know that an increase in the price of the good itself (coffee) causes a movement along the demand curve, not a shift of the demand curve.
Understand that if tea is a complement to coffee, an increase in the price of tea would decrease the demand for coffee, shifting the demand curve to the left, not to the right.
