Graphing a Demand Curve from a Demand Schedule, and How to Read a Demand Graph

The demand curve is the line in a supply and demand graph that shows consumer behavior: at a given market price, how many units will consumers purchase? (Or, reading the chart in the opposite direction, how much is the marginal buyer willing to pay for the nth unit?)

Key topics in the video include:

• Definition of the demand curve
• Graphing a demand curve, starting from data in a demand schedule
• Why the demand curve slopes downward
• Two ways to read a demand curve: horizontal and vertical (and how each helps us understand consumer preferences and behavior in the market)
