Which term describes the axis that runs horizontally on a standard coordinate plane?

• A. Axis labels
• B. X-axis
• C. Percent
• D. Units

Answer: (B)

The horizontal line on a standard Cartesian coordinate plane is called the x-axis. It runs left to right and carries the x-values, while the vertical line is the y-axis. The other terms aren’t describing the axis itself: axis labels are just the names placed on the axes, percent is a type of value, and units are measurements. So the correct term for the horizontal axis is the x-axis.
