It is not possible to answer the question with no information about which ordered pairs!
there are none, ordered pairs come from equations like x = 2y -5
Coordinates
You didn't show the Ordered Pairs so there is no way this question could be answered.
Relationship can also be represented by a set of ordered pairs called a function.
There is one ordered pair for every arrow in a mapping diagram. The ordered pair represents the mapping from one element in the domain to one element in the codomain.

A set of ordered pairs, can also be tables, graphs, or a mapping diagram

This statement is incorrect. A mapping diagram can represent both functions and relations. A relation is any set of ordered pairs, while a function is a specific type of relation where each input (or domain element) is associated with exactly one output (or range element). In a mapping diagram, if each input has a single output, it represents a function; if an input has multiple outputs, it represents a relation that is not a function.
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
To accurately identify the function represented by a mapping diagram, one would need to analyze the specific pairs of inputs and outputs shown in the diagram. A mapping diagram typically illustrates how each element from the domain is associated with an element in the range, indicating whether the function is one-to-one, onto, or neither. If you can provide details about the diagram, I can help determine the type of function it represents.
The Ordered Pairs are 1x20, 2x10, and 5x4.
A coordinate plane has infinitely many ordered pairs: each and every point in the plane is represented by an ordered pair. There may be a small number of points that are identified for a specific reason: for example the vertices of a triangle or quadrilateral and so you may have a few ordered pairs that are specifically labelled.

Infinitely many. Each and every point on the graph gives rise to an ordered pair.
-1 is a one-dimensional entity. It can have no equivalent in ordered pairs.
