To graph the inequality \( x \leq -3 \), you need to represent all the values of \( x \) that are less than or equal to \(-3\).
1. **Closed Point**: Since the inequality includes equal to (denoted by the "≤"), you will use a closed point at \(-3\) to show that \(-3\) is included in the solution set.
2. **Arrow**: You will then draw an arrow extending indefinitely to the left from \(-3\) to indicate all the numbers less than \(-3\).
Given these details, the correct representation would be:
- A closed point at \(-3\).
- An arrow extending indefinitely left from this point.
Therefore, the correct choice is the one that shows a closed point at \(-3\) with an arrow extending left.
