Plotting points in the coordinate plane is a fundamental concept in mathematics that involves representing data or positions using a two-dimensional grid system. The coordinate plane consists of two perpendicular number lines called the x-axis and the y-axis. The x-axis runs horizontally, while the y-axis runs vertically.

When plotting points, each point is specified by its coordinates, which are written as an ordered pair (x, y). The x-coordinate represents the horizontal position of the point, and the y-coordinate represents the vertical position.
