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 85 miles per hour. The ball will travel 235 feet when hit by a bat swung at 45 miles per hour and will travel 337 feet when hit by a bat swung at 79 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? A ball will travel feet farther for each mile-per-hour increase in the speed of the bat. (Type a whole number.) The number (in millions) of employees working in educational services in a particular country was 12.1 in 2005 and 17.5 in 2014. Let x = 5 correspond to the year 2005, and estimate the number of employees in 2013. 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 estimate the requested quantity. Let y represent the number of employees. The linear equation that best models the number of employees (in millions) is (Simplify your answer. Use integers or decimals for any numbers in the equation. Round to the nearest hundredth as needed.)
