Assume that the data can be modeled by a straight line and that the trend continues indefinitely. Use two data points to find such a line and then answer the question. Suppose a baseball is thrown at 82 miles per hour. The ball will travel 352 feet when hit by a bat swung at 53 miles per hour and will travel 448 feet when hit by a bat swung at 77 miles per hour. Let y be the number of feet traveled by the ball when hit by a bat swung at x miles per hour. How much farther will a ball travel for each mile-per-hour increase in the speed of the bat?
