Liam and Sarah have each drawn a line on the scatter plot shown below: The graph shows numbers from 0 to 10 on x and y axes at increments of 1. Dots are made at the ordered pairs 1, 7 and 2, 6 and 3, 5.5 and 4, 5.8 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 2.9 and 9, 2.2 and 10, 1.5. A straight line labeled Line A joins the ordered pairs 0, 7.2 and 10.4, 0. A straight line labeled Line B joins the ordered pairs 0, 7.2 and 9.8, 0. Which line best represents the line of best fit? (1 point) Line A, because it shows a positive association Line A, because it is closest to most data points Line B, because it is closest to most data points Line B, because it shows a negative association
