Question

which number line represents the solution set for the inequality $-\frac{1}{2}xgeq4$?

Explanation:

Step1: Solve the inequality

Multiply both sides of $-\frac{1}{2}x\geq4$ by - 2. When multiplying an inequality by a negative number, the direction of the inequality sign changes. So we get $x\leq - 8$.

Step2: Interpret on number - line

The solution set $x\leq - 8$ is represented on a number - line as a closed circle at - 8 (because the inequality includes equality, $\leq$) and an arrow pointing to the left (towards smaller numbers).

Answer:

The number - line with a closed circle at - 8 and an arrow pointing to the left represents the solution set.
