Solution

Three mutually perpendicular lines divide the whole space into 8 equal parts. Each part is called octant.
The names of octants are $O X Y Z, O X Y Z^{'}, O X Y^{'} Z, O X^{'} Y Z, O X^{'} Y^{'} Z, O X^{'} Y Z^{'}, O X^{'} Y Z^{'}, O X^{'} Y^{'} Z^{'}$
The octants in which both $x -$ and $y -$ coordinates are negative are $O X^{'} Y^{'} Z, O X^{'} Y^{'} Z^{'}$
