Question 152543
Not sure I understand what you're asking.
Is it
{{{y=abs(1)+2}}}?
Typically you have a x and y variable when you want to graph something. 
You have neither. 
Could you please check and re-post your question?
If it's 
{{{y=abs(1)+2}}}
Then
{{{y=1+2}}}
{{{y=3}}}
Here's that graph. 
{{{drawing( 300, 300, -5, 5, -5, 5,grid( 1 ),green(line( -8, 3, 8, 3)))}}}
