If I wanted to determine how the weight of a? gas-powered car,? x, affects gas? mileage, y using the below data represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year. How would I find the least-squares regression line treating weight as the explanatory variable and miles per gallon as the response variable, ^ y = __ x + __ and also interpret the slope y-intercept, if appropriate?
