The three representative points shown here are used to find the two parallel lines and, finally, the median-median line for data points that are not shown.
The median-median line is two-thirds of the vertical distance from the top line to the bottom line.
Find the centroid, or balance point, of the triangle formed by the three representative points. Remember, the centroid is the point (, ). Will the three representative points always form a triangle? Write an equation of a line that passes through the centroid and has the same slope as the line through (2, 11) and (8, 41). Compare this equation with the median-median equation given by your calculator. Describe your results. Make some conjectures based on your observations.
