Option aNegative

All Options:

  • ANegative
  • BPositive
  • CConstant
  • DZero

Detailed Solution & Explanation

To understand the slope of the demand curve, we need to consider the law of demand, which states that as the price of a product increases, the quantity demanded decreases, and vice versa. • The demand curve is a graphical representation of this relationship between price and quantity demanded. • The slope of the demand curve represents the change in quantity demanded in response to a change in price. • According to the law of demand, as the price increases, the quantity demanded decreases, which means that the demand curve slopes downward from left to right. • This downward slope indicates a negative relationship between price and quantity demanded, which is why the slope of the demand curve is generally negative. The incorrect options, such as a positive slope, would imply that as the price increases, the quantity demanded also increases, which contradicts the law of demand. • A constant or zero slope would imply that changes in price have no effect on the quantity demanded, which is not a realistic representation of consumer behavior in most markets.
