I'm thinking quadrants would be the answer.
The coordinate plane is formed by the intersection of a vertical and a horizontal number line. What is the horizontal number line called?
Are the four quadrants.
Quadrant.
A coordinate plane! If it has one or more breaks in it is not a coordinate plane but only a part of one.
The xy or Cartesian or coordinate plane.
Those are the four "quadrants".

point of origin
The intersection point is called the origin.

The x-axis typically intersects the y-axis in a coordinate plane at the origin, or 0,0. One can renumber either or both axis, resulting in a different intersection point, but that is usually done only in specialized cases.
