Copy this into your notebook. A coordinate plane is a plane containing a horizontal number line, the x-axis, and a vertical number line, the y axis. The intersection of these axes is called the origin. The axes divide the coordinate-plane into four regions called quadrants, which are numbered I, III, and IV.
