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)

The slope of the equation is -6.035 which means that for each increase in weight by 1,000 pounds, the highway gas mileage decreases by 6.035 miles per gallon. In other words, the heavier the vehicle, the lower its gas mileage tends to be.
