For a horizontal demand curve,
A: the slope is undefined, and the price elasticity of demand is equal to 0.
B: the slope is equal to 0, and the price elasticity of demand is undefined.
C: both the slope and price elasticity of demand are undefined.
D: both the slope and price elasticity of demand are equal to 0.
A: the slope is undefined, and the price elasticity of demand is equal to 0.
B: the slope is equal to 0, and the price elasticity of demand is undefined.
C: both the slope and price elasticity of demand are undefined.
D: both the slope and price elasticity of demand are equal to 0.
举一反三
- The slope of the demand curve is not the same as the price elasticity of demand because the slope of a demand curve ( ) A: compares percentage changes in quantity demanded and price. B: compares absolute changes in quantity demanded and price. C: obeys the law of demand. D: is not constant when the demand curve is linear.
- A straight-line demand curve with negative slope intersects the horizontal axis at 200 tons per week. The point on the demand curve at which the price elasticity of demand is 1 corresponds to a quantity demanded A: of 0 tons. B: of 100 tons. C: of 200 tons. D: that would be negative if a negative quantity demanded were possible.
- When demand is inelastic the price elasticity of demand is
- Price elasticity of demand along a linear, downward-sloping demand curve increases as price falls. A: 正确 B: 错误
- 中国大学MOOC: Price elasticity of demand along a linear, downward-sloping demand curve increases as price falls.
