What is a coordinate plane?

Explanation:
A coordinate plane is the two-dimensional surface created by two perpendicular axes—the horizontal x-axis and the vertical y-axis. Their intersection is the origin, and points are plotted using ordered pairs (x, y): move x units along the x-axis from the origin, then y units along the y-axis from there. This setup describes flat space, so it can display all pairs of numbers in two dimensions. If you had a third axis, the z-axis, you’d be in three-dimensional space instead. The other descriptions refer to three-dimensional space or to a line, not a coordinate plane.
