When looking at expressions like this,, you need to remember that the square root of a negative number does not exist in the set of Real Numbers. This means that there is no way to simplify this expression,, making the correct answer to your question Undefined.
Let me know if you have any further questions.

The compass heading is 242.5deg
1/3 (0.333,,,) is 0.05666... away from 0.39 .
2/5 (0.4) is 0.01 away .
3.8 (0.375) is 0.015 away .
9/25 (0.36) is 0.3 away .
2/5 is the closest one.
Plug them in... -4=x -5=y
-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)
-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)
Therefore the ordered pair IS NOT the solution.
Hope this helps :)
