Which number line shows the solution set for |m| = 4

Answer:
Last choice that shows points on +4 and -4 is the correct graph.
Step-by-step explanation:
We have been given equation [tex]|m|=4[/tex]. Now we need to find out which of the given number lines shows the corret solution set for [tex]|m|=4[/tex].
We know that [tex]|x|=a[/tex] can be broken into two parts as:
[tex]x=+a[/tex] and [tex]x=-a[/tex]
Same way we can break [tex]|m|=4[/tex] into two parts as:
[tex]m=+4[/tex] and [tex]m=-4[/tex]
Hence last choice that shows points on +4 and -4 is the correct graph.
