What term describes a two-dimensional plane defined by the x and y axes?

• A. Divide
• B. Equilateral Triangle
• C. XY Coordinate Plane
• D. Quadrilateral

Answer: (C)

This question tests understanding of what the two-dimensional surface formed by the x-axis and y-axis is called. That plane is the coordinate plane, often called the Cartesian plane, where points are written as ordered pairs (x, y). The term that specifically names this plane in the prompt is the XY coordinate plane, which describes exactly that same surface. The other terms refer to shapes or concepts that aren’t a plane: a divide implies a split, an equilateral triangle is a triangle with equal sides, and a quadrilateral is a four-sided polygon.
