Unformatted text preview: The vertical axis in Figure 1 depicts the price per unit of good X measured in dollars, while the horizontal axis depicts the quantity demanded of good X measured in units of good X . In addition to the demand schedule and the demand curve, the buyers' demand for a good can also be expressed a third way—algebraically, using a demand equation . The demand equation relates the price of the good, denoted by P , to the quantity of the good demanded, denoted by Q . For example, the demand equation for good X corresponding to the demand schedule in Table 1 and the demand curve in Figure 1 is From the demand equation, you can determine the intercept value where the quantity demanded is zero, as well as the slope of the demand curve. In the example above, the intercept value is 10 and the slope of the demand curve is −2. In order to satisfy the law of demand, the slope of the demand the slope of the demand curve is −2....
