Exploring Adding and Subtracting Rational Expressions

The video tutorial introduces the coordinate plane, explaining its components such as the x-axis, y-axis, quadrants, and origin. It covers how to understand and write ordered pairs, and how to plot points on the coordinate plane. The tutorial also includes a real-world application, demonstrating how to use coordinates to map locations in a town.
