Amalia and Alec are studying the growth of a plant over time. They measure the height of the plant at the end of each week for several weeks and display the data in a scatter plot. Then they find the equation for the line of best-fit to be y 5 2.5 1 1. 25x, where x represents the week and y represents the height of the plant at the end of the week. They want to use the equation to estimate when the height of the plant will be 10 inches. Amalia’s estimate is after Week 6, and Alec’s estimate is after Week 15. Is either student correct? Explain.
