Which term describes the two-dimensional plane used for plotting data and locating points?

• A. Graph
• B. Coordinate Plane
• C. Coordinate System
• D. Matrix

Answer: (B)

The key idea is recognizing the surface used to plot points in a flat, two-dimensional space. The two-dimensional plane used for plotting data and locating points is the coordinate plane. It is the flat surface created by the intersection of the two perpendicular axes (usually labeled x and y), where each point is described by an ordered pair (x, y). This distinguishes it from the entire coordinate system, which is the framework that includes the axes, origin, and scales used to assign coordinates. A graph, in contrast, is a specific plotted representation of a relation or function on that plane, and a matrix is simply a grid of numbers used in linear algebra, not the plotting surface.
