Question

Which number line represents the solution set for the inequality –x ≥ 4?

Answer 1

X would be l-xl     X>4  

Answer 2

x ≤ -4

See number line attached below.

Explanation:

Given : inequality –x ≥ 4

We have to represent the given inequality –x ≥ 4 on number line.

Consider the given inequality, –x ≥ 4

Multiply both side by -1 , this reverses the inequality.

x ≤ -4

Now, all numbers which are less than and equal to - 4 will be marked on number line (as shown below)
