This is a poorly written question - just my opinion.

If I had to pick an answer, I would select --> decrease the slope of line n

How is it a poor question if it has a picture? :P

directrix · Answer

A diagram does not ensure a good question. 

I see at least two answers: you could keep line m stationary and decrease the slope of m. 
You could decrease the slope of line m and then decrease that of n to match the decrease.

So the answer is both then? :P
