or

say I have x and y in columns

take the first x and y (X1,Y1)

take the last x and y (Xe/Ye)

fit a straight line to those two points for example by saying

(y-Y1) (Ye-Y1)

----- = ----

(x-X1) (Xe-X1)

That will give you the equation of the line through those two points.

Then try the other points in that equation. If they work, all the points are on the line through the first and last points.
