Which axis on a two-dimensional graph is used to measure height from the origin?

• A. Y axis
• B. X axis
• C. Origin
• D. Z axis

Answer: (A)

Height from the origin is read on the vertical axis. In a standard two-dimensional graph, the horizontal axis runs left to right (the X axis) and the vertical axis runs up and down (the Y axis). The height of a point above the origin corresponds to its y-coordinate, which tells you how far up the point is from (0,0). The origin is where the two axes cross, at (0,0). The Z axis belongs to three-dimensional graphs to show depth, not height on a 2D plane. For example, a point with coordinates (3, 5) is 5 units up from the origin and 3 units to the right.
