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. They then find the equation for the best-fit line to be y = 2.5 + 1.25x, where x represents the number of weeks that have passed and y represents the height of the plant at the end of each week. They want to use the equation to estimate when the height of the plant will be 10 inches. Amalia's estimate is after 6 weeks, and Alec's estimate is after Week 15. Is either student correct? Explain.
