Final Answer

On the coordinate plane, the number line that runs up and down is the y-axis.

Explanation

In the Cartesian coordinate system, there are two perpendicular number lines that form the axes. The horizontal line is known as the x-axis, where the x-coordinates of points are measured, while the vertical line is called the y-axis, which measures the y-coordinates of points. Each point on the plane is represented as an ordered pair (x, y), where 'x' corresponds to the location on the x-axis and 'y' relates to the location on the y-axis. Understanding the distinction between these axes is essential for graphing equations and navigating the coordinate system effectively. The y-axis, specifically, allows us to represent vertical relationships and is crucial for visualization in various mathematical contexts.
