Answer:
You have to move 6 times to the left and 6 times down.
Step-by-step explanation:
If you're at (2,0), you move 2 times to the left, and then you're at (0,0). 
Next move 4 times to the left. Now you're at (-4,0).
Now, move 6 times down, and now, you're at (-4,-6).  
 
        
                    
             
        
        
        
N=3
Because 6+6=12
