Which number line represents the solution set for the inequality -1/2 x ≥ 4?

Answer 1

-1/2 x ≥ 4

First, solve for x by multiplying both sides of the inequality by -2. When you multiply or divide an inequality by a negative number, it flips the inequality sign. So the ≥ becomes a ≤.

x ≤ -8

x less than or equal to -8 looks like:

<==|==|==•----|----|--->

-10 -9 -8 -7 -6
