Table 4 lists U.S. crude oil production as a percentage of total U.S. energy production for selected years. Let x represent years since 1960 and y represent the corresponding percentage of oil production.
(A) Find the equation of the line through (0, 35) and (40,17), the first and last data points in Table 4.
(B) Find the equation of the line through (0, 35) and (10,32), the first and second data points in Table 4.
(C) Graph the lines from parts (A) and (B) and the data points (x,y) from Table 4 in the same coordinate system.
(D) Use each equation to predict oil imports as a percentage of total consumption in 2020.
(E) Which of the two lines better represents the data in Table 4? Discuss.
