Another researcher for an environmental agency is investigating fuel economy. He has developed a linear model for city 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=−4.086w+32.96
Interpret the y-intercept of this equation.(1 point)
