Figure 4.4
A relation establishes a way to discern ordered pairs.
Figure 4.5
A set relation provides a standard way to generate ordered pairs of numbers.
the paired numbers relate to each other. Dealing with the ordered pairs Figure 4.4
illustrates, for example, you can observe that as you go from 1 to 8, you can detect
a pattern. The pattern is that if you begin with the first number and add 1, then
you get the second number. As Figure 4.5 illustrates, you can proceed to
mathematically express the relationship.
As shown in Figure 4.6, when you are dealing with ordered pairs, a number line
becomes an effective starting place for making mathematical translations of the
relationships you observe.
