Kim and Sonia 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, 5 and 2, 4 and 3, 3.5 and 4, 2.5 and 4.5, 2.8 and 5, 2 and 6, 1.5 and 7, 1 and 8, 0.9 and 9, 0.2 and 10, 0. 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, 5 and 9.1, 0.
Which line best represents the line of best fit? (1 point)
Line A, because it shows a negative association
Line A, because it is closest to most data points
Line B, because it is closest to most data points
