What is a demand curve and supply curve, use diagrams to illustrate?

A demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded by consumers. It shows the quantity of a good or service that consumers are willing and able to purchase at different prices. The demand curve slopes downwards from left to right, indicating that as the price of a good decreases, the quantity demanded increases.

A supply curve, on the other hand, is a graphical representation of the relationship between the price of a good or service and the quantity supplied by producers. It shows the quantity of a good or service that producers are willing and able to supply at different prices. The supply curve slopes upwards from left to right, indicating that as the price of a good increases, the quantity supplied also increases.

Here are diagrams illustrating a demand curve and a supply curve:

The point where the demand curve and supply curve intersect is known as the equilibrium point, where the quantity demanded equals the quantity supplied at a specific price. This is the price at which the market clears and there is no excess supply or demand.

Demand Curve

- A graphical representation of the relationship between the price of a good or service and the quantity demanded by consumers.
- Slopes downward, indicating that as the price increases, the quantity demanded decreases, and vice versa.

- X-axis: Price
- Y-axis: Quantity demanded

Factors that Shift the Demand Curve:

- Income of consumers
- Tastes and preferences
- Price of substitutes
- Price of complements
- Expectations about future prices

Supply Curve

- A graphical representation of the relationship between the price of a good or service and the quantity supplied by producers.
- Slopes upward, indicating that as the price increases, the quantity supplied also increases, and vice versa.

- X-axis: Price
- Y-axis: Quantity supplied

Factors that Shift the Supply Curve:

- Number of producers
- Production costs
- Technology
- Government regulations

Equilibrium Point

- The price and quantity at which the demand and supply curves intersect.
- At this point, the quantity supplied equals the quantity demanded, creating a balance in the market.

- Equilibrium price: The price at which the equilibrium point occurs.
- Equilibrium quantity: The quantity of the good or service bought and sold at the equilibrium point.
