A plane in three dimensional space is determined by:
Three NON COLLINEAR POINTS
Two non parallel vectors and their intersection.
A point P and a vector to the plane.
So I can't prove that in analytic geometry.

I think the answer of Francisco is very good. However, I might phrase it a little differently --
- three noncollinear points determine a unique plane - that is, one and only one plane
- three collinear points determine an infinite number of planes -- that is, many planes can pass through the same line.
