E) always negative whereas the slope is always positive.

 

85) Which of the following is correct?

i.All linear demand curves have a constant slope and a constant price elasticity of demand.

ii.The price elasticity of demand changes while moving along a downward-sloping linear demand curve.

iii.The magnitude of the slope of all linear demand curves is equal to the price elasticity of demand.

A) i only

B) ii only

C) iii only

D) i and ii

E) i, ii, and iii

 

86) Moving downward along a linear (straight-line) downward sloping demand curve, the

A) slope is constant.

B) price is constant.

C) quantity is constant.

D) elasticity is constant.

E) None of the above answers is correct.

87) Moving downward along a linear (straight-line) downward-sloping demand curve, the

A) price elasticity of demand does not change.

B) quantity demanded decreases.

C) demand becomes more elastic.

D) demand becomes less elastic.

E) total revenue never changes.

 

88) As you move up along a straight-line demand curve,

A) the price elasticity of demand decreases in size.

B) the price elasticity of demand increases in size.

C) total revenue always decreases.

D) total revenue always increases.

E) total revenue never changes.

 

89) Which of the following statements is correct for the price elasticity of demand along a linear, downward-sloping demand curve?

A) The price elasticity of demand is constant because the slope is constant.

B) At low prices, demand is elastic but at high prices demand is inelastic.

C) At high prices, demand is elastic but at low prices demand is inelastic.

D) The price elasticity of demand is not defined for a linear demand curve because the slope is constant.

E) None of the above answers is correct.

90) At the midpoint of a linear, downward-sloping demand curve, the price elasticity of demand is

A) greater than one.

B) equal to one.

C) less than one but greater than zero.

D) zero.

91) Along a linear (straight-line) downward-sloping demand curve, demand is unit elastic at

A) the highest price.

B) the lowest price.

C) the midpoint.

D) all points on the linear demand curve.

E) None of the above because linear demand curves are never unit elastic.
