What is the term for a line on a graph showing how much of a good will be bought at different prices?

• A. Price
• B. Demand
• C. Supply curve
• D. Demand curve

Answer: (D)

The line on a graph showing how much of a good will be bought at different prices is the demand curve. It represents the quantity demanded at each price, illustrating the Law of Demand: when price falls, quantity demanded tends to rise, all else equal. The curve is drawn with price on the vertical axis and quantity demanded on the horizontal axis, and it typically slopes downward from left to right. This is distinct from the overall concept of demand, which is the relationship between price and quantity demanded, and from the supply curve, which shows quantities supplied at different prices. Price is simply the amount charged, not the graphical representation.
