As shown below...

In this case i will assume that you mean $[x] -= |x|$

Now we must graph $y= |x|$ first of all...

This just mean the line $y = x$ but where there are any negative values of $y$ we make them there possitive counterpart...

$y = |x| :$
graph{y =|x| [-9.67, 10.33, -3.56, 6.44]}

Now we can just perform the tranformation of shiting it down by $5$ :

$y = |x| -5$ :

graph{y = |x| -5 [-9.295, 10.705, -8.16, 1.84]}
