I can’t see the scatterplot you mean. To answer which pair the best-fit line passes through I need the plot image or the coordinates of P, Q, R, S, T.
If you can upload the picture or give the points’ (x,y) coordinates I’ll determine the least-squares line and tell you which two points lie on it.
If you want to do it yourself, use these steps:
1. Compute x̄ and ȳ (the means of the x and y values).
2. Compute slope m = Σ(xi−x̄)(yi−ȳ) / Σ(xi−x̄)².
3. Compute intercept b = ȳ − m·x̄.
4. Check which points satisfy yi = m·xi + b (within rounding error). Those are the points the line passes through.
Send the image or coordinates and I’ll finish it for you.
