The relation between two different ordered pairs which have the same first coordinate is simply that. They have the same first coordinate. If you mark the two points on graph paper, you find that one always lies directly above or below the other. The relationship is that they both belong to the family of points which make up a particular vertical line.
The domain is all the first coordinates in a relation. A relation is two ordered pairs.
Ordered pairs
A coordinate plain
A relation is defined as a set of ordered pairs. A function is a special kind of relation ...
its the x coordinate (first number) It is the set of values that the x coordinate can take.

The first coordinate is traditionally horizontal coordinate, often labelled as "x".
The domain is all the first coordinates in a relation. A relation is two ordered pairs.
A set of ordered pairs is a relation. Or Just simply "Coordinates"
If a set of ordered pairs is not a relation, the set can still be a function.
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.
they are the first set of paired elements

A relation is a set of ordered pairs
You can locate any point on the coordinate plane by an ordered pair of numbers (x,y), called the coordinates.
