# Do we consider a point in a coordinate system to be a scalar?

Knowing that a scalar quantity doesn't change under rotation of a coordinate system. Do we consider a point in a Cartesian coordinate system (i.e. A (4,5)) a scalar quantity? If yes, why do the components of point A change under rotation of the coordinate system?
According to my understanding, the point A (4,5) is not considered scalar. Am I right?
