Those of you interested in this question might be interested in a dynamic
Powerpoint Presentation which compares two sets of n-points. Each has the same
Sy and Sx but a different r. [Note: As I remember, I think the numerical
scales are off a bit, but that is a fine point that does not effect the concept
shown in the demonstration.]

It is available on our class web site:
Then select "Investigate/Explain" and then "Understanding slope= r(Sy/Sx)"
under downloadable PowerPoint Documents.
