Question 24 3 pt An engineer determined that the weight of a car and gas mileage have a linear relationship. A car that weighs 3600 pounds has a gas mileage of 18 miles per gallon. Another car that weighs 2600 pounds has a gas mileage of 25 miles per gallon. Let x be the weight of the car and y be the gas mileage of the car in miles per gallon. Use the point-slope formula to write a linear equation....
