Answer 2

• x < 9
• any rational less than 9

Explanation:

The number line has an open circle at 9, and is shaded to the left. This represents numbers less than, but not including 9.

In general, a number line includes all numbers, both rational and irrational. Between any two points, there are an infinite number of each category of numbers. So, you could say the graph represents rational numbers only, and it would look no different from a graph that represent all real numbers.
