Understanding the Coordinate Plane

This video tutorial reviews the vocabulary related to the coordinate plane. It introduces the origin, x-axis, and y-axis, and explains how each point on the plane is represented by a pair of coordinates. The video also covers how to locate points using these coordinates and discusses the four quadrants of the plane, including their naming conventions using Roman numerals. The tutorial concludes with a review of the basic vocabulary.
