# Elasticity and Slope with Linear Demand

Elasticity and Slope with Linear Demand

The price elasticity of demand is the percentage change in the quantity of the good demanded associated with a one percent increase in the price of the good. This Demonstration lets you explore the relationship between elasticity and slope for the case of linear demand functions. Use the button bar to select either elasticity calculated at a point or the midpoint (arc) formula commonly used in introductory texts.
