Example
Q: Find the length, midpoint, and slope of the segment joining points (-1, 4) and (8,1).
Solution: Run DISTANCE. How?

The program reports
the x- and y- values of
the midpoint.
Press ENTER for more.
The program reports
the slope.
Interpretation:
The length is about 9.4, or √90,
which is 3√10 (use RADICALN to
simplify).
The midpoint is (7/2 , 5/2).
The slope is -1/3.
