A researcher for an environmental agency is investigating fuel economy. She has developed a linear model for highway gas mileage, g, in terms of the vehicle weight, w, in thousands of pounds using a representative sample of car types. The equation is g=−6.035w+46.33
Interpret the slope of this equation.(1 point)
