Mastering Two-Dimensional Geometry: And Applying The Coordinate Plane

coordinate plane

a plane in which a horizontal number line and vertical number line intersect at their zero points

The coordinate plane is a two-dimensional plane used to locate specific points using two coordinates, which are generally represented by two perpendicular number lines called the x- and y-axis. The horizontal number line is the x-axis, and the vertical number line is the y-axis. In this plane, every point is uniquely determined by a pair of coordinates, written in the form (x, y).

The point (0,0) is known as the origin and acts as the reference point for finding other points in the coordinate plane. The x and y coordinates of any point can be found by measuring its distance parallel to the x-axis and y-axis, respectively.

The coordinate plane is useful in various fields such as mathematics, physics, and engineering. It is used to plot the graphs of different equations such as linear, quadratic, and cubic functions, as well as to find the solutions to different problems that involve two-dimensional geometry. Additionally, it can be used to analyze and graph the data collected in various experiments, surveys, and studies.
