The x coordinate.
x
Evaluate the function at the first number in the pair. If the answer is not equal to the second value, then the ordered pair cannot be in the function.
Conventionally the x co-ordinate.
If the reflection is over the x value, the x-value does not change.

y
Evaluate the function at the first number in the pair. If the answer is not equal to the second value, then the ordered pair cannot be in the function.
Conventionally the x co-ordinate.
An ordered pair has two values. You need to define the absolute value of an ordered pair before the question can be answered. There are many possible metrics.
If the reflection is over the x value, the x-value does not change.

y
Given the ordered pair (3, y), what value of ywould make the ordered pair a solution of the equation 4x − 2y = 24?12
The ordered pair IS the coordinates on the graph. If you have the ordered pair (1,2) that means the value of x is 1 and the value of y is 2, so to get to that point on a graph from the origin (center) you would move right 1 unit and up 2 units.
A ordered pair is one of many ways in which a function may be defined. The function maps the element in the first position of an ordered pair to the second element in that pair.

The rule for a set of ordered pairs is the statement that states the relationship of of a certain value to another value.For example:given the set of ordered pair { (1,2) , (3,4) , (5,6) , (7,8) }we notice that the value of y is increased by 1 as the value of x varies.For instance, in the first ordered pair which is (1,2) where 1 is x and 2 is y such that (x,y), 1 increased by 1. In other words, x is increased by 1.So we say that the rule of the ordered pair is:{(x,y) | y = x + 1 }read as "The set of ordered pairs such that y is equal to x plus one"
