What is the ordered pair rule?

Answer 1

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"
