An individual demand curve shows the quantity of the good, a consumer would buy at different prices. Distribute a copy of Activity 3 to each student. 3. Generally, a higher price encourages firms to produce more. That’s right! Point out the intersection of the drawn supply and demand curves. Sometimes, these curves can represent the supply curve of an individual firm, or the demand curve of an individual consumer, but generally economists use these … Understanding economic equilibrium. The graph for the following situation is shown above. D (demand) = 20 - 2P (price). This makes almost no sense. It is also clear from the above analysis that the demand function is made up of all the demand curves D 1 D 1, D 2 D 2, etc. Compute the equation of a linear supply curve. Ask students what they think will happen that will move the market toward equilibrium; that is, eliminate the surplus. [D. Ask students to plot the data from the supply schedule and draw a graph on their graph paper. A higher price makes the good more profitable to produce.
