## What is an example of an ordered pair?

An ordered pair is a pair of numbers in a specific order. For example, (1, 2) and (- 4, 12) are ordered pairs. The order of the two numbers is important: (1, 2) is not equivalent to (2, 1) — (1, 2)≠(2, 1).

## What is an ordered pair?

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. In the Cartesian plane, we define a two-dimensional space with two perpendicular reference lines, namely x-axis and y-axis.

## What is an ordered pair in simple terms?

An ordered pair is two numbers for which the order in which they are given is important. Ordered pair usually refers to a set of two numbers used to locate a point in a coordinate plane. When an ordered pair refers to the location of a point in the coordinate plane, they are called the coordinates of the point.

## What is ordered pair in sets?

A function f from a set A to a set B is a set of ordered pairs {(x, y)} such that x in the set A and y is the in the B. For every x ∈ A there is exactly one y ∈ B such that (x, y) is an ordered pair in f. We call this element f(x).

## What is the first number in an ordered pair called?

Think How do we distinguish between the two number lines? Circle all of the numbers on the x-axis. Box all of the numbers on the y-axis. An ordered pair is a pair of numbers that describes the location of a point in the coordinate plane. The first number is called the x-coordinate.

## What does an ordered pair look like?

Ordered pairs are sets of numbers used for plotting points. They are always written inside parentheses, and are separated by a comma. Ordered pairs are usually seen together with a four-quadrant graph (also called a coordinate plane). This is a grid that looks like graph paper on which two perpendicular lines cross.

## What is another name for ordered pair?

Ordered pairs are also called 2-tuples, or sequences (sometimes, lists in a computer science context) of length 2.

## Why do we use ordered pairs?

An ordered pair is used to show the position on a graph, where the “x” (horizontal) value is first, and the “y” (vertical) value is second. Also in the co-ordinate system, ordered pair is used to locate a point. Pairs in math are denoted by (,) and are generally considered to be ordered.

## What is the first element of an ordered pair?

We call the first element of an ordered pair the first coordinate, and we call the second element of an ordered pair the second coordinate. To use ordered pairs to represent a function, we let the inputs be the first coordinates and the outputs be the second coordinates.

## What is the difference between ordered pair and unordered pair?

In mathematics, an unordered pair or pair set is a set of the form {a, b}, i.e. a set having two elements a and b with no particular relation between them, where {a, b} = {b, a}. In contrast, an ordered pair (a, b) has a as its first element and b as its second element, which means (a, b) ≠ (b, a).

## Which ordered pair represents a function?

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function.

## What is the best way to identify an ordered pair?

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

## What is Cartesian product and ordered pair?

In mathematics, specifically set theory, the Cartesian product of two sets A and B, denoted A × B, is the set of all ordered pairs (a, b) where a is in A and b is in B. In terms of set-builder notation, that is. A table can be created by taking the Cartesian product of a set of rows and a set of columns.
