What the second number in a ordered pair?

Answer 1

In an ordered pair, the second number is referred to as the "y-coordinate." It represents the vertical position of a point on a Cartesian plane, indicating how far up or down the point is located relative to the horizontal axis (x-axis). The first number in the pair is the "x-coordinate," which indicates the horizontal position. Together, they define a specific location in a two-dimensional space.
