A. They have negative reciprocal slopes
The original points/point c would be (-8,11) bc the y stays the same and the x changes from its original to (in this case) negative to positive
(positive to negative/negative to positive for either the x or y)
hope this helps
the mean can be misleading, because there outlier (77), which is not close to the ages of the others, thereby changing the mean drastically.
hope this helps
