When comparing data
A Cartesian coordinate plane system specifies each point uniquely in a plane by a pair of numerical coordinates. These coordinates are the signed distances from the point to two fixed perpendicular directed lines often called the x and y axis. The measurements on the axes are same units of length. The use of x and y to name is axes is common, but there are many other ways to name them.
Possibly because the first time that pupils are introduced to the name and concept it is has only two dimensions. These are usually represented as horizontal (x) and vertical (y) coordinates. Actually, many children meet the concept - in its 1-dimensional form - as the number line. It is not called a Cartesian coordinate system then, and they make only simple use of it. The Cartesian coordinate system is normally extended to 3-dimensional space in high school coordinate geometry when it is obviously not called a plane, and to multi-dimensional hyperspaces in advanced mathematics or physics.
You do not have to. You could use polar coordinates, if you prefer.

Yes! By expanding the system to 3D!
Descartes used the parabola to illustrate algebraic equations. He put these equations on a visible plane using the Cartesian coordinate system and they sometimes took the shape of a "u" curve, or a parabola.
It is possible, but you need to use three axes.
coordinate plane was created by the Romans
We assign coordinates to point on the plane and use those coordinates to tell us about the points. For example, the distance formula tells us how far apart they are, the midpoint formula tells us where there midpoint is. All of these and much more depend looking at a point as an ordered pair, (x,y) in the coordinate plane.The coordinate system is determined by the two directed lines and the given unit length. When the directed lines intersect at a right angle, the system is Cartesian, and (x,y) are Cartesian coordinates of the point. Normally, x-axis and y-axis are chosen so that an anticlockwise rotation of one right angle takes the positive x-direction to the positive y-direction. There are other methods of assigning coordinates to points in the plane. one such is the method of polar coordinates. The coordinate plane is the main idea in analytic geometry.
(x,y,z) hi APEX ppl! TB
