The speed at which you drive a car can affect the car's fuel economy. The July 2008 Consumer Reports magazine reported the Toyota Camry has a fuel economy of 40 miles per gallon (mpg) at 55 miles per hour (mph), and 30 mpg at 75 mph.
- What is the independent and dependent variables?
- What would be the linear equation in slope intercept form of this problem?
- What would be a reasonable domain and range?
Hey! Sorry if it just seemed this was me getting answers or anything. I think that the independent variable would be mph and dependent would be mpg, however when I got converted into slope intercept form, my y-intercept was 67.5. I am not sure if I am going about this problem correctly and continue to solve it different ways and now I am confused whether the y intercept is 135. I am also unclear about the practical domain and range of this would be and I have to graph this problem.
