Question

graph the inequality on the number line.
$rleq - 9$

Explanation:

Step1: Identify the critical point

The critical point for the inequality $r\leq - 9$ is $r=-9$.

Step2: Determine the type of point

Since the inequality is $\leq$, we use a closed - circle at $r = - 9$.

Step3: Determine the direction of the graph

The values of $r$ are less than or equal to $-9$, so we draw an arrow to the left of $-9$ on the number line.

Answer:

On the number line, place a closed - circle at $-9$ and draw an arrow to the left.
