Answer:
Line R
Step-by-step explanation:
we know that
A line of best fit is a straight line that best represents the data on a scatter plot.
This line may pass through some of the points, none of the points, or all of the points.
From the given graph the line R passes through 2 points. The number of points above the line is equal to the number of points below the line.
therefore
Line R is the line of best fit
