I've read thru the thread  interesting points. You might also like to try the
Excel Graph Wizard, which is dead easy once you get the hang of it. (I've shown
it to grades 5 and 6 for graphing experimental data )
Enter your xy data set, highlight the lot, click on graph wizard, Use the
XY scattergraph option, then follow the instructions.
Once you have a graph of points in a line, you can right click on one of the
data points you have graphed and add a trendline. If your data is strictly from
a linear function, you can get the equation of the set by choosing "add
trendline, clicking the options tab checking "display equation on chart"
The thing I like about this routine is it takes data gathered in the classroom,
can give a best fit, it works without the internet, it is extendable to
nonlinear functions and it's generally available.

I'm not likely to post again here predictably. If you like the possibilities, I
suggest you follow your interest in Excel graph wizard by playing with it and
maybe trying it on your students. I have found it especially useful for science
data.
The hardest hurdle to jump involves students who are convinced that only bar
graphs have meaning as data graphs.
