What are Ordered Pairs?

In mathematics, an ordered pair is a pair of values in which the order of the values is important. It is a way to represent a relationship between two variables, where each variable is associated with a specific value. Ordered pairs are commonly used in algebra, geometry, and other branches of mathematics to represent points on a coordinate plane, relationships between variables, and other mathematical concepts.

Representing Ordered Pairs

Ordered pairs are typically represented using parentheses, with the first value inside the first set of parentheses and the second value inside the second set of parentheses. For example, the ordered pair (a, b) represents the relationship between the variables a and b, where a is associated with the value inside the first set of parentheses and b is associated with the value inside the second set of parentheses.

Example Ordered Pairs

Let's consider some examples of ordered pairs:

(a, b) represents the relationship between the variables a and b.
(x, y) represents the relationship between the variables x and y.
(3, 4) represents the relationship between the variables 3 and 4, where 3 is associated with the value 3 and 4 is associated with the value 4.

The Relation as a Set of Ordered Pairs

Now, let's consider the relation as a set of ordered pairs. A set is a collection of unique elements, and in this case, the elements are the ordered pairs.

A. Ordered Pairs: $\{(-1,-2),(0,1),(3,2)\}$

This set of ordered pairs represents the relationship between the variables x and y, where x is associated with the values -1, 0, and 3, and y is associated with the values -2, 1, and 2.

(-1, -2) represents the relationship between the variables x and y, where x is associated with the value -1 and y is associated with the value -2.
(0, 1) represents the relationship between the variables x and y, where x is associated with the value 0 and y is associated with the value 1.
(3, 2) represents the relationship between the variables x and y, where x is associated with the value 3 and y is associated with the value 2.

B. Ordered Pairs: $\{(-2,-1),(1,0),(3,2)\}$

This set of ordered pairs represents the relationship between the variables x and y, where x is associated with the values -2, 1, and 3, and y is associated with the values -1, 0, and 2.

(-2, -1) represents the relationship between the variables x and y, where x is associated with the value -2 and y is associated with the value -1.
(1, 0) represents the relationship between the variables x and y, where x is associated with the value 1 and y is associated with the value 0.
(3, 2) represents the relationship between the variables x and y, where x is associated with the value 3 and y is associated with the value 2.

C. Ordered Pairs: $\{(-2,-1),(0,1),(2,3)\}$

This set of ordered pairs represents the relationship between the variables x and y, where x is associated with the values -2, 0, and 2, and y is associated with the values -1, 1, and 3.

(-2, -1) represents the relationship between the variables x and y, where x is associated with the value -2 and y is associated with the value -1.
(0, 1) represents the relationship between the variables x and y, where x is associated with the value 0 and y is associated with the value 1.
(2, 3) represents the relationship between the variables x and y, where x is associated with the value 2 and y is associated with the value 3.

D. Ordered Pairs:

This option is not provided, so we will not consider it.

Conclusion

In conclusion, ordered pairs are a fundamental concept in mathematics that represent relationships between variables. They are used to represent points on a coordinate plane, relationships between variables, and other mathematical concepts. The relation as a set of ordered pairs is a way to represent a relationship between two variables, where each variable is associated with a specific value. By understanding ordered pairs, we can better understand mathematical concepts and relationships.
