There is a surface given as an array by a set of points (x, y, z), which has a slope. It is necessary to find the equation of the plane as close as possible to a given uneven surface, and subtract this plane (remove the slope) from the uneven surface.
The whole question is, what methods exist for finding the equation of such a plane?

You need to start with the phrase, "Hey, toaster, google for me!". Well, okay.
1. You need to approximate your points (x, y, z) with a plane.
