  • B.

B

Difficulty: Easy

Category: Heart of Algebra / Inequalities

Strategic Advice: Solve the inequality using inverse operations. Then compare your answer with each of the number lines shown. Remember, on a number line, numbers to the right are greater than numbers to the left.

Getting to the Answer:

There should be an open dot at –6, with shading to the right, so (B) is correct. Don't be fooled by C. You only reverse the inequality symbol when you multiply or divide by a negative number, not when the answer is negative.
