Final answer:
Along a linear downward-sloping demand curve, the price elasticity of demand will be elastic.
Step-by-step explanation:
The price elasticity of demand along a linear downward-sloping demand curve is elastic. This means that a change in price will result in a larger percentage change in quantity demanded. Along the demand curve, if the price changes by 1%, the quantity demanded will change by 0.45%. For example, a 10% increase in price will result in a 4.5% decrease in quantity demanded, and a 10% decrease in price will result in a 4.5% increase in quantity demanded.
