Coordinate plane

The coordinate plane is a two-dimensional plane formed by two perpendicular number lines, the x-axis and the y-axis. The point where these two number lines intersect is called the origin and is often represented as (0,0). The x-axis represents the horizontal axis, and the y-axis represents the vertical axis.

Each point in the coordinate plane has a unique set of coordinates, represented by an ordered pair (x, y), where x represents the value on the x-axis and y represents the value on the y-axis. The x-coordinate tells us the position of the point along the horizontal axis, and the y-coordinate tells us the position of the point along the vertical axis.

The coordinate plane is often used to graph equations, plot points, and visualize geometric shapes. It allows us to represent mathematical concepts and analyze relationships between variables.
