Vector equation of a plane passing through a given point and normal to a given vector - Vector Form

The vector equation of a plane ‘Pi’ passing through a point having position vector a and normal to vector n is (r-a).n = 0 or r.n = a.n.

Where r is the position vector of an arbitrarily chosen point.

It can also be written as r.n = d
Where d = a.n
