Understanding Three-Dimensional Coordinates

A two-dimensional coordinate system is formed by two perpendicular lines designated as an x-axis and a y-axis. The two lines meet at a point called the origin. With a three-dimensional coordinate system, a third axis line is added. The third axis line intersects the other two axis lines at the origin, forming right angles with each of them. The x-axis shows locations of points in space lying in front and back of the origin. The y-axis shows the location of points in space to the left and to the right of the origin. The z-axis shows points in space lying above and below the origin.

One way to visualize a three-dimensional coordinate system is to imagine yourself standing in a room near one of its corners, and facing the corner. The x-axis extends along the base of the...
