Question

graph.
x ≤ -640
to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.

Explanation:

Step1: Identify the endpoint

The inequality is \(x\leq - 640\), so the endpoint is at \(x = -640\). Since the inequality includes equality (\(\leq\)), the endpoint is closed.

Step2: Determine the direction of the ray

The inequality \(x\leq -640\) means all values of \(x\) that are less than or equal to \(-640\). On the number - line, this is to the left of \(-640\).

Answer:

Plot a closed circle at \(-640\) on the number - line and draw a ray to the left.
