Exploring the Coordinate Plane and Its Quadrants

In this video, Jeff Jacobson introduces the concept of the coordinate plane, explaining its formation using horizontal and vertical number lines, known as the x-axis and y-axis. He describes the four quadrants formed by these axes and their properties, including the origin point at (0,0). The video also covers how to identify points using ordered pairs, with examples demonstrating how to plot points and describe their locations on the coordinate plane.
