Up and down axis
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.

The coordinate plane is formed by the intersection of a vertical and a horizontal number line. What is the horizontal number line called?
Graphing or plotting.
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)
It can be just about anything, depending what you are graphing.
A coordinate plane has two axes and four quadrants. The horizontal number line is called the x-axis and the vertical line is called the y-axis.
"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3
Coordinate plane worksheets are needed for fourth grade and up because fourth grade is when you learn basic graphing and that is when you would need a coordinate plane worksheet.
