This expression is used by economists to allow for a proper explanation of a situation. Price Theory Demand Schedule. The quantity demanded of a good or service is defined as the quantity of the good or service consumers are willing to buy at a particular price at a particular point in time.

The image defines Quantity Demanded as "the quantity of a good or service consumers are willing to buy at a particular price at a particular point in time."

The table provides the following points for the demand curve:

• $(Qd=0, P=8)$
• $(Qd=1, P=7)$
• $(Qd=2, P=6)$
• $(Qd=3, P=5)$
• $(Qd=4, P=4)$
• $(Qd=5, P=3)$

The graph shows Price (P) on the y-axis and Quantity (Q) on the x-axis.

• At $P=8$, the curve starts at $Q=0$.
• At $P=7$, the curve passes through $Q=1$.
• At $P=6$, the curve passes through $Q=2$.
• At $P=5$, the curve passes through $Q=3$.
• At $P=4$, the curve passes through $Q=4$.
• At $P=3$, the curve passes through $Q=5$.

All the points from the demand schedule are correctly plotted on the graph, and the curve connecting them accurately represents the demand curve.

The graph correctly plots the demand curve based on the provided schedule.
