Explanation / Answer
use your graphing calculator to input the data. [Stat], [Edit] and then input x-values under L1 and y-valuesunder L2 after that, to find regression equation, go [Stat], [Calc] andthen choose the 4th option LinReg(ax+b). your line ofregression should be: y = -0.00797x + 54.695 so to predict the fuel consumption for a car that weighs 3000lbs, y = -0.00797(3000) + 54.695 = 30.785 mi/gal
