2. one goal for the united states is to be able to generate 20% of its electricity by the year 2030 using wind power. if the country used the same amount of electricity in 2030 as it did in 2012, how much of the electricity (in terawatt hours) would be generated by wind power? what ordered pair can you use to represent this value?
3. using the two data points from exercises 1 and 2, write a linear equation that shows how the wind power would need to grow to make this goal. use years for the independent variable and terawatt hours for the dependent variable. let year 0 represent year 2012.
a. write your equation in slope-intercept form.
b. explain what the slope and y-intercept represent in this situation.
c. insert a graph of your line.
