The coordinate plane, also known as the Cartesian plane, is a two-dimensional grid used to represent points and graph mathematical equations or relationships. It is formed by two perpendicular number lines, known as the x-axis and y-axis, that intersect at their zero points, called the origin.
The x-axis is the horizontal line, while the y-axis is the vertical line. The point where they intersect, typically denoted as (0,0), represents the origin of the coordinate plane.
Every point on the coordinate plane can be represented by an ordered pair (x, y), where x denotes the distance along the x-axis and y denotes the distance along the y-axis. The x-coordinate corresponds to the position of the point horizontally, relative to the origin, while the y-coordinate corresponds to the position of the point vertically, relative to the origin.
To locate a specific point (x, y), you start from the origin and move along the x-axis horizontally to the right if x is positive or to the left if x is negative. Then, from that point, you move vertically along the y-axis upwards if y is positive or downwards if y is negative.
On the coordinate plane, positive x-values are to the right of the origin, negative x-values are to the left, positive y-values are above the origin, and negative y-values are below.
The coordinate plane is a valuable tool for representing and analyzing various mathematical concepts, such as plotting equations, determining distances between points, and solving geometric problems.
