Coordinates are a system of numbers that describe the location of a point in space. They are used in many different fields, such as mathematics, physics, geography, and engineering.
The most common coordinate system is the Cartesian coordinate system, which uses two numbers, called the x-coordinate and the y-coordinate, to locate a point in a two-dimensional plane. The x-coordinate measures the distance of the point from the origin (the point where the x-axis and y-axis intersect) along the x-axis. The y-coordinate measures the distance of the point from the origin along the y-axis.
