Calculate trend line

Joe
I need to add a trend line to a scatter plot (not automatically supported by
the charting package) but I don't know how to calculate it. Is there any
formulas around for calculating what the trend line should look like?

Thanks but I was looking for an actual function or library. Since I'm not a
math major this is going to take a while to figure out.
