[AI-generated answer — Bot GPT 3.5]

To find the solution to the inequality, we need to isolate x on one side of the inequality sign. First, we add 9 to both sides of the inequality to get:

4x - 9 + 9 ≥ -21 + 9

This simplifies to:

4x ≥ -12

Next, we divide both sides of the inequality by 4 to solve for x:

4x/4 ≥ -12/4

This simplifies to:

x ≥ -3

So, the solution to the inequality is x ≥ -3.

On a number line, this would be represented by a closed circle on -3 and a line extending to the right.

The number line that represents the solution of the inequality 4x - 9 ≥ -21 is:
