coordinate plane
a system for locating points in two dimensions that uses a horizontal axis and a vertical axis
The coordinate plane is a two-dimensional graph that is used to plot and analyze mathematical functions or relationships between two variables. It consists of two perpendicular number lines, the x-axis and the y-axis, that intersect at a point called the origin.
The x-axis is the horizontal axis and represents the values of one variable, while the y-axis is the vertical axis and represents the values of another variable. Together, the x- and y-axes divide the coordinate plane into four quadrants.
Each point on the coordinate plane has a unique set of coordinates that specify its location. The x-coordinate represents the position of the point along the x-axis, while the y-coordinate represents the position of the point along the y-axis.
The coordinates of a point are written as an ordered pair (x, y), where x is the x-coordinate and y is the y-coordinate. For example, the point (3, 4) represents a point that is 3 units to the right of the origin and 4 units above the origin.
The coordinate plane is used in a variety of mathematical and scientific applications, including geometry, algebra, calculus, physics, and engineering. It is also used in the study of data and statistics, where points represent data points in a plot or graph.
