Understanding the Cartesian Coordinate System

This video tutorial introduces the basic concepts of coordinate geometry, including the x-axis, y-axis, and quadrants. It explains how coordinates are used to locate points on a plane and introduces the Cartesian coordinate system. The tutorial also outlines key concepts such as the distance formula, section formula, and calculating the area of a triangle using coordinates.
