We have, y equals x minus open vertical bar x close vertical bar
When x  0,  = x  y = x - x = 0
When x < 0, = -x y = x + x = 2x

The given function is equivalent to

y equals open curly brackets table attributes columnalign left end attributes row cell 0 space i f space x greater or equal than 0 end cell row cell 2 x space i f space x less than 0 end cell end table close
So, the graph of this function is as follows
