The Cartesian Plane is a two-dimensional surface defined by two perpendicular lines called axes. The horizontal line is known as the x-axis, while the vertical line is called the y-axis. These axes intersect at a point called the origin, which has the coordinates (0, 0). The plane is divided into four quadrants, each representing different combinations of positive and negative values for x and y. Points on the Cartesian Plane are represented by ordered pairs, written as (x, y). The first number indicates the position along the x-axis, and the second number indicates the position along the y-axis. This system allows for precise location and analysis of geometric shapes, functions, and data in mathematics and various fields.
