(1, 1) refers to a point in Cartesian coordinates where x = 1 and y = 1. It represents a location on a two-dimensional plane.
A system that uses perpendicular lines intersecting at right angles to create coordinates for locating points on a plane.
Origin: The point where both axes intersect (0, 0). It serves as a reference for measuring distances from it.
Quadrant: Any one of four regions into which space or an object can be divided by two perpendicular coordinate axes.
