Copyright © 2007 Pearson Education, Inc. Publishing as Pearson Addison-Wesley Slide Features of the Three-Dimensional Cartesian Coordinate System The axes are labeled x, y, and z, and these three coordinate axes form a right-handed coordinate frame. The Cartesian coordinates of a point P in space are an ordered triple, (x, y, z). Pairs of axes determine the coordinate planes. The coordinate planes are the xy-plane, the xz-plane, and the yz-plane and they have equations z = 0, y = 0, and x = 0, respectively. The coordinate planes meet at the origin (0, 0, 0). The coordinate planes divide space into eight regions called octants. The first octant contains all points in space with three positive coordinates.
