With absolute value, you can get a negative value and a positive value in between those two lines. 
So....What numbers could you plug in for k to give you -3 and 3 in between the lines? :)

anonymous · Answer

um 9..?

anonymous · Answer

-9 will give you -3. But you need one more value that'll give you 3.
Remember that you'll be getting two values as your answer when it comes to absolute value :3

anonymous · Answer

Can it be 9 or -3?

anonymous · Answer

its c because absolute value makes the value positive so-9+6= -3 and if it is positive it is 3 and -3+6=3 and it is already positive so therefore it is C

@Ariarose: It's both. Now just match those numbers to the choice that has those two values, and there you go! :)
