Wind energy is one type of renewable energy that does not produce dangerous greenhouse gases as a by-product. The graph shows the consumption of wind energy in the United States for selected years. The variable y represents the amount of wind energy in trillions of Btu, and the variable x represents the number of years since 2000.
a. Use the points (0, 57) and (4, 143) to determine the slope of the line.
b. Interpret the slope in the context of this problem?
c. Use the points
d. If this linear trend continues beyond the observed data values, use the equation in part (c) to estimate the consumption of wind energy in the year 2010.
