Answer:
R and Q
Explanation:
Line of best fit is line on a graph that shows the general direction that a group of points seem to follow.
If we look at the scatterplot the line of best fit seems to pass by the R and Q because the points on the scatterplot seem to follow the line R and Q
Where the lines passing through the points P and Q , P and T, or S and Q does not seem to represent the actual line of best fit. Since these lines do not represent a direction that a group of points seem to follow.
