Mar 15, 2023 · How Does the Demand Curve Work? On a demand curve graph, you plot prices on the vertical axis (or y-axis) and quantities on the horizontal axis (or x-axis). The demand curve below shows demand in a market for lemons. As you can see, the per unit price of lemons is on the vertical axis.

- Price vs. Quantity Demanded. Economists generally agree that price is the most fundamental determinant of demand. In other words, price is likely the most important thing that people consider when they are deciding whether they can buy something.
- Slope of Demand Curve. The law of demand states that, all else being equal, the quantity demanded of an item decreases as the price increases, and vice versa.
- Plotting Downward Slope. If you're still confused as to why the demand curve slopes downward, plotting the points of a demand curve may make things clearer.
- Calculating Slope. Since slope is defined as the change in the variable on the y-axis divided by the change in the variable on the x-axis, the slope of the demand curve equals the change in price divided by the change in quantity.
To answer those questions, we need the ceteris paribus assumption. A demand curve or a supply curve is a relationship between two, and only two, variables: quantity on the horizontal axis and price on the vertical axis.
A change in the price of a good or service causes a change in the quantity demanded—a movement along the demand curve. A change in a demand shifter causes a change in demand, which is shown as a shift of the demand curve. Demand shifters include preferences, the prices of related goods and services, income, demographic characteristics, and ...
