It is quite easy although apparentely undocumented :) (I couldn't find 
it in the Windows help file)
Double click your graph. In the Customize Chart dialog: select from the 
object tree on the top left corner the Series you want to add the Trend 
Line to. Click on the "+ Add" button under it and from the drop list 
select the Trend Line model you want to adjust to your data (e.g. Linear)

Good luck with your presentation.
