There are two main factor that make ocean water more or less dense than about 1027 kg/m3:

-3 times 2 is -6 and 2 times 2 is 4. So after the transformation we are left with (-6,4).
Since 900 is just 360 to times plus 180; rotating it basically means that it will end up in the same place and if we rotated it 180. These means we need to switch the signs on the numbers (positive to negative and vice-versa). Which gives us the answer of (6,-4).
