Which term describes the two-dimensional plane grid used for locating points on a plane?

• A. Graph
• B. Coordinate System
• C. Planar grid
• D. Coordinate Plane

Answer: (D)

The key idea is that points on a flat surface are located using coordinates on a specific plane, defined by the horizontal and vertical axes. This two-dimensional setting, with its x- and y-axes and the grid that helps you plot points, is the coordinate plane. It’s the actual surface where you read and place ordered pairs like (3, -2). A graph is more about representing a relationship or function, not just the plane you plot on. A coordinate system describes how coordinates are assigned and measured, but the grid itself that you use to locate points sits on the coordinate plane. Planar grid isn’t a standard term for this context.
