Damn, your right!

What I need to do is calculate the slope of the line first then establish whether or not the data is on the correct side of the slope.

There are some Mighty Quick Algorithms for this. I think I remember seeing one in the Algorithms In Perl book. "Don't divide" is an imporant part of that.

As it happens, the sample chapter of Mastering Algorithms with Perl is all about geometry, and it includes a discussion of the standard ray method for the point-in-polygon problem.
