I have sets of coordinates which contain
3 points in each set.
Can anyone suggest how I can test if
all 3 points are collinear (to within say 3 or 4 decimal places)
Or can anyone show me how to simply display
the formula for the line using each pair of points in turn
and displaying all 3 formulas. In the form y=mx+b
Any help would be much appreciated.
Thanks
