Understanding the Cartesian Plane and Coordinate System

This video tutorial covers the basics of working with the Cartesian coordinate plane. It explains how to identify and plot points using ordered pairs, with a focus on scaling the axes for accurate representation. The tutorial also demonstrates how to modify the scaling of both horizontal and vertical axes to better identify coordinates. Finally, it provides examples of plotting points on the graph, emphasizing the importance of understanding input and output values.
