The Coordinate System

The video tutorial introduces the concept of using number lines to represent quantities, such as distances on a chessboard. It explains how to create a coordinate plane by intersecting horizontal and vertical number lines, known as the x-axis and y-axis, respectively. The origin is the intersection point where counting begins. The tutorial further explains how to locate points on the coordinate plane using x and y coordinates, which represent distances from the origin. The coordinate system is a method to determine the position of points on the plane, exemplified by chess pieces' positions.
