How to graph |x|+|y|=1?

 |x|+|y|=1
 
would you isolate for y: |y|=1-|x| and then consider x when x<0 and x>0?

The graph is a square with corners at (0, 1), (1, 0), (-1, 0), and (0, -1)

square. That's right, because |x| must not ever exceed 1 because if it were to do so, the right side would become negative, and |y| cannot equal a negative number.  So the testing process of any x values whose absolute value > 1 reveals necessary prohibitions.
