planar coordinates

Planar coordinates are a way to specify locations on a flat surface, like a graph or map, using two numbers: the x-coordinate (horizontal position) and the y-coordinate (vertical position). Think of it as a grid where each point can be identified by its distance from a central point, often called the origin. For example, in the coordinate pair (3, 2), "3" indicates how far to move right from the origin, while "2" shows how far to move up. This system helps in visualizing and locating objects in a two-dimensional space.
