What is the two-dimensional surface used for plotting points with ordered pairs?

• A. Coordinate Grid
• B. Graph
• C. Cartesian Plane
• D. Matrix

Answer: (A)

The main idea here is recognizing where we plot points described by ordered pairs. The two-dimensional surface used for this is the Cartesian coordinate plane. It has two perpendicular axes, the x-axis and the y-axis, that intersect at the origin, with units marked so you can locate any point (x, y). Each ordered pair tells you how far to move along the x-axis and then along the y-axis to reach that point on the plane. The grid lines you see on the plane—the coordinate grid—help you read and place these points, but the surface itself is the Cartesian (coordinate) plane. A graph is a broader term for a visual representation of data or a function, not specifically the plotting surface. A matrix is just a rectangular arrangement of numbers and isn’t used to plot points on this plane.
