Content-2021 Spring Term (1) X HReview Test Submission: Quiza 4 X O Lumen O https ohm.lumenlearning.comassess2/ Alejandro is selling HDMI cables on eBay, and is trying to determine the best price to sell at. For the last 10 weeks, he has adjusted his price slightly each week and tracked the number of cables he sold. He plotted the results, and drew a line he feels fits the data well. 300 250 200 150 100 50 3.25 3.5 3.75 4 4.25 4.5 4.75 Price (S) a) The line of best fit passes through the points (3.50, 270) and (4.75, 210). Find an equation for the line.
