( / means absolute value)
Solve: 3+/2y1/>=1. Graph the solution set on a number line.
The number line I have is:
5 4 3 2 1 0 1 2 3 4 5 6
I'm confused on what to do.

3+ │2y1│ ≥ 1 or
│2y1│ ≥ 2
this has an intuitive solution.
by the definition of absolute value, the left side can only be positive or zero.
any positive value or zero ≥ 2
so the solution would be the entire number set. So draw a solid line on your number line with arrows in either direction. 
I have to show my work so is that ALL I have to do? 3+ ©¦2y1©¦ ¡Ý 1 or
©¦2y1©¦ ¡Ý 2 
by saying,
"by definition │anything│ ≥ 2" you have shown your work.
