To graph the inequality \( x \leq -3 \), you should use a closed point on -3 to indicate that -3 is included in the solution, and then draw an arrow extending indefinitely to the left, indicating all numbers less than -3 are included as well.
Therefore, the correct response is:
A number line ranges from negative 8 to 2 in increments of 1. A closed point is plotted at negative 3. An arrow extends indefinitely left from the closed point past negative 8 along the number line.
