Which of the following correctly describes the coordinate system in mathematics? - The coordinate system defines a set of rules for drawing shapes on a graph without specifying their positions. - The coordinate system provides a method to determine the position of a point by using two perpendicular lines intersecting at a fixed origin. - The coordinate system uses only a single axis to describe the position of points in a plane. - The coordinate system is exclusively used for plotting polynomial functions and does not apply to other types of equations.
