Price-demand. A company manufactures notebook computers. Its marketing research department, using statistical techniques, collected the data shown in Table 9 , where p is the wholesale price per computer at which x thousand computers can be sold. Using special analytical techniques (regression analysis), an analyst produced the following price-demand function to model the data: p x = 2000 − 60 x 1 ≤ x ≤ 25 (a) Plot the data points in Table 9 , and sketch a graph of the price-demand function in the same coordinate system . (b) What would be the estimated price per computer for a demand of 11 , 000 computers? For a demand of 18 , 000 computers?

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
