The Ordered Pairs are 1x20, 2x10, and 5x4.
-1 is a one-dimensional entity. It can have no equivalent in ordered pairs.
Y is the second number in a set of ordered pairs.
One such synonym would be coordinates, which is also the proper way of naming the ordered pairs on a Cartesian coordinate plane.
A relation is defined as a set of ordered pairs. A function is a special kind of relation ...
The Ordered Pairs are 1x20, 2x10, and 5x4.
It is not possible to answer the question with no information about which ordered pairs!
-1 is a one-dimensional entity. It can have no equivalent in ordered pairs.
Y is the second number in a set of ordered pairs.
Ordered pairs that have a negative x and a positive y are in the second quadrant.
Ordered pairs are used for many things. Anytime you graph a point on a cartesian coordinate system, you have an ordered pair. In fact, all of R^2 is made up of ordered pairs. When you put a value in a function and get one out, you have an ordered pair
there are none, ordered pairs come from equations like x = 2y -5
If a set of ordered pairs is not a relation, the set can still be a function.
Yes. That's why it is called "ordered".
Coordinates
You didn't show the Ordered Pairs so there is no way this question could be answered.
There are infinitely many ordered pairs. One of these is (0, 0).
