I presume that you have done a little bit vector geometry.

You can write the equation:

A, B, C ) \cdot \vec{x} +D=0" alt="P A, B, C ) \cdot \vec{x} +D=0" />

The vector (A,B,C) is the normal(?) vector of the plane and stands perpendicular to the plane.

D divided by the absolute value of vector (A,B,C) gives the distance of the origin to the plane.
