The coordinate plane consists of?

• A. A grid with perpendicular axes
• B. Only horizontal lines
• C. Only vertical lines
• D. A single axis

Answer: (A)

The coordinate plane is a grid created by two perpendicular axes that cross at the origin. There’s a horizontal axis that runs left to right and a vertical axis that runs up and down, and together they form the grid used to locate points with ordered pairs (x, y). This setup gives the four quadrants and a way to plot every point on the plane. The other options describe only part of the picture (horizontal lines only, vertical lines only, or a single axis) and don’t capture the full grid and two crossing directions that define the coordinate plane.
