# What is an ordered pair formula?

## What is an ordered pair formula?

Ordered pairs are often used to represent two variables. When we write (x, y) = (7, – 2), we mean x = 7 and y = – 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.

How do you find the ordered pairs of a function?

To calculate the ordered pair for any equation we replace one of the variables with any integer or a rational number and solve for the remaining variable. By this, we get values for both the variables that satisfy the given equation.

How do you find the number of ordered pairs?

Proof is simple, for every element a of A, there are total Size(B) elements of type (a,b) for b in B. Thus Size(B) + Size(B) + …. , Size(A) times = Size(A) Size(B). In order pair the first element is set of X and second element is set of Y.

### How do you solve ordered pairs?

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.

How to find the number of ordered pairs?

Given a positive integer N, the task is to find the number of ordered pairs (X, Y) where both X and Y are positive integers, such that they satisfy the equation 1/X + 1/Y = 1/N. Explanation: Only 3 pairs { (30,6), (10,10), (6,30)} satisfy the given equation. Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Can a graph be written as an ordered pair?

The solution to a two-variable equation or graph of an equation can also be written as an ordered pair. Below are three of the unlimited many solutions to the equation y = -x + 3: (-1, 4), (0, 3), and (2, 1). We can verify this by testing whether or not:

#### Which is the second component of an ordered pair?

In an ordered pair, say (x,y),x is called the ﬁrst component and y is called the second component. To ﬁnd ordered pairs that satisfy an equation such as y=2 x+3, we can choose any value for one variable, then ﬁnd the corresponding value for the other variable by substituting into the equation.

Can a vector be represented as an ordered pair?

Since the three points are on the graph of y = -x + 3, shown above, the ordered pairs are solutions to the equation. In physics, a vector can be represented as an ordered pair, , where the first number is called the vector’s x-component and the second number is called the vector’s y-component.
