Question

graph the inequality below on the number line. a≥ - 9

Explanation:

Step1: Identify the inequality

The inequality is \(a\geq - 9\).

Step2: Determine the type of endpoint

Since the inequality is \(\geq\), we use a closed - circle at \(a=-9\) on the number line.

Step3: Shade the appropriate region

We shade to the right of \(a = - 9\) because values of \(a\) that are greater than or equal to \(-9\) are to the right of \(-9\) on the number line.

Answer:

On the number line, place a closed - circle at \(-9\) and shade to the right of \(-9\).
