You might look here for some great graphing software, points as well as
function;

Also, Graphmatica, a superb 2D grapher, supports point graphs and regression
etc.  More than enough, perhaps.  Found at archives.math.utk.edu.

I used a plotting 'racecar' game that would give a good sense of the effects
causing change in 2 dimensions.  Very simple rules, nice game for young teens.
Not numerical coordinate points as in the above, but a good sense of the effect
of two dimensional change as the 'cars' accelerate and decelerate [or not] while
changing direction around a curve.  It's tough to describe here without images.
Email for more info if interested and I'll put together a more detailed
description.

David.
