Coordinate plane
It is called the x axis and the vertical number line is the y axis
In the co-ordinate plane The horizontal number line is the 'x-axis'. The vertical number line is the y-axis. They intersect at the 'origin' ; coordinate (0,0) In the 3-dimensional system there is a third number line going from front to back , this is the z-axis. All three axes intersect at the origin , and have the the coordinates ( x,y,z) = (0,0,0)
The center of the cartesian coordinate plane is called the origin and is located at the point (0,0), where the x and y axis meet.
The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
Coordinate plane
The xy or Cartesian or coordinate plane.
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.

Quadrant.
Those are the four "quadrants".
(0,0) = the origin
I'm thinking quadrants would be the answer.
The horizontal number line on a coordinate plane is called the x-axis, and the vertical number line on a coordinate plane is called the y-axis.
Up and down axis
In the co-ordinate plane The horizontal number line is the 'x-axis'. The vertical number line is the y-axis. They intersect at the 'origin' ; coordinate (0,0) In the 3-dimensional system there is a third number line going from front to back , this is the z-axis. All three axes intersect at the origin , and have the the coordinates ( x,y,z) = (0,0,0)
