Question

graph the inequality below on the number line. a < 9

Explanation:

Step1: Identify inequality symbol

The symbol '<' means less than.

Step2: Locate the number on number - line

Locate 9 on the number - line.

Step3: Determine the circle type

Since it is a strict inequality ($a < 9$), we use an open circle at 9.

Step4: Shade the appropriate region

We shade the region to the left of 9 to represent all values of $a$ that are less than 9.

Answer:

On the number - line, place an open circle at 9 and shade the line to the left of 9.
