I dont know if there is an inbuilt function, but i have managed to do so previously by using IF statements and adding extra data in the spreadsheets.
 
That looks slick, but how does it work? Typing the same formula in a new spreadsheet gives a #NAME error?
 
Download the file and open in EXCEL. Alt F11 and read, it's is fairly well documented.
 
The reason you need to download the file is that the function is a custom function, otherwise, it would simply be a usage tip.

Ah! I was pressing ALT+F8 to edit/view the macro and it would only show my personal macros. Still not quite sure the difference between a visual basic script and a macro.
 
One and the same in Excel 5.0 and up

Don't forget the old fashioned way - scale it off
 
If your data is truly linear you could get the slope and y-intercept for both lines using the LINEST() function and use Goal Seek or Solver.
