n 2009, U. S. families spent, on average, $570 for back-to-school supplies. The number rose to $655 in 2015. Let y represent the average amount of back-to-school spending and x the number years since 2009. Find a linear equation that fits the data and use your equation to predict the back-to-school spending in 2032.
