If  is some point on the plane, then it forms a vector  with the given point on the plane . Since a normal vector on a plane is orthogonal to any vector lying on the plane, this vector  is therefore perpendicular to the normal vector  of the plane.
This implies that .
Thus the equation of the plane is .
