In an ordered pair, the second number is called the y-coordinate.

Explanation:

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space (a Cartesian plane). It is written in the form (x, y), where 'x' represents the x-coordinate, and 'y' represents the y-coordinate. The x-coordinate indicates the horizontal position of the point, while the y-coordinate indicates the vertical position. Therefore, in the context of your statement, the second number in the ordered pair corresponds to the y-coordinate, which defines the point's position along the vertical axis. This structure is fundamental in various mathematical applications, including graphing equations and representing relationships between variables.
