Verified step by step guidance

1. Understand that elasticity in economics measures responsiveness or sensitivity of one variable to changes in another variable.
2. Recall that the price elasticity of demand measures how much the quantity demanded of a good changes in response to a change in its own price.
3. Recognize that income elasticity of demand measures how quantity demanded changes in response to changes in consumer income.
4. Identify that cross-price elasticity of demand specifically measures how the quantity demanded of one good responds to changes in the price of a different good.
5. Conclude that cross-price elasticity helps determine whether two goods are substitutes (positive cross-price elasticity) or complements (negative cross-price elasticity).
