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
