Both the slope of the demand curve and the elasticity of demand are measures of how consumers alter their quantities demanded in response to changes in price.How are the two concepts different from each other? Given a negatively sloped straight-line demand curve,how will slope and elasticity differ? Given a vertical or horizontal demand curve,how will they differ?
