Natural Resources Canada tests new vehicles each year and reports several variables related to fuel consumption for vehicles in different classes. For 2015, it provides data for 526 vehicles that use regular fuel. Two variables reported are carbon dioxide (CO2) emissions and highway fuel consumption. CO2 is measured in grams per kilometer (g/km), and highway fuel consumption measured in liters per 100 kilometers (L/km). The correlation between these two variables, to six decimal places, was found to be r = 0.980516.

Required:
Find the equation of the least-squares regression line for predicting CO2 emissions from highway fuel consumption.
