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)

Origin
A line.Unless the two planes are the same, in that case a plane.
The coordinate plane is formed by the intersection of a vertical and a horizontal number line. What is the horizontal number line called?

Do you mean the two angles that are formed by two intersecting lines? If yes, they are called vertical angles and they are congruent.
Limestone is formed in layers called Bedding Planes and the vertical cracks are called Joints. The horizontal cracks are not given a specific name - however I am sure someone will want to contradict this
Right angles (90 degrees) will be formed.
