ELASTICITY AND DEMAND SLOPE: The slope of a straight-line demand curve, one with a constant slope, has constantly change elasticity. No two points on a straight-line demand curve as the same elasticity. The point of intersection between the demand curve and the vertical, price axis is perfectly elastic (E = ∞). The intersection point between the demand curve and the horizontal, quantity axis is perfectly inelastic (E = 0). The exact middle, or midpoint, of the demand curve is unit elastic (E = 1). The segment between the midpoint and the price-axis intercept is relatively elastic (1 < E < ∞). The segment between the midpoint and the quantitY-axis intercept is relatively inelastic (0 < E < 1).

- Competition among buyers forces them to spend their limited incomes on the most satisfying goods.
- Less competition among sellers than among buyers lets the sellers charge higher prices.
- Less competition among buyers than among sellers lets the buyers pay lower prices.
