Projection of the plane onto a line:

The matrix A projects the plane in the direction of the  eigenvector V2  on a line  determined by the eigenvector V1 if : 
         
* The eigenvector V1 has its eigenvalue equal to  one and
* The eigenvector V2 has its eigenvalue equal to zero and

* If The vectors V1 and V2 are linearly independent
