Y is the second number in a set of ordered pairs.
The domain is the set of the first number of each ordered pair and the range is the set of the second number.
Ordered pairs are used to locate points on the graph. The first number in an ordered pair corresponds to the horizontal axis, and the second corresponds to the vertical axis.
It is the abscissa.
Ordered pairs are used in graphing, with the x axis first in the pair. Example: (5,7) (x,y)

The convention for the Cartesian coordinate system is, the first number is the x coordinate, and the second number is the y coordinate. That's the order.
Traditionally, ordered pairs are given with the x value first and the y value second: (x,y).
The Ordered Pairs are 1x20, 2x10, and 5x4.
its the x coordinate (first number) It is the set of values that the x coordinate can take.
Each ordered pair is made up of two numbers. A linear graph has an infinite number of pairs. An easy way to see this is look at the line y=x. This is a linear graph and any two of the same numbers will work! So there are an infinite number of ordered pairs.
