1. The problem asks to identify which inequality is represented on a number line. 2. The number line shows a filled circle at 3 and an arrow extending to the left toward negative infinity. 3. A filled circle at 3 means the value 3 is included, so the inequality uses \(\leq\) or \(\geq\). 4. The arrow pointing left means values less than or equal to 3, so the inequality is \(x \leq 3\). 5. Among the options, \(x \leq 3\) corresponds to option B. Final answer: B. \(x \leq 3\)
