The best method to solve this is by drawing the possible lines(2 for line m and 2 for line k) on the co-ordinate plane, you can easily spot the answer.
Took me less than a minute to solve this.
Good question though!

Re: S99-20 [#permalink]
I just have a silly doubt regarding the slope calculation in this question .

You have written slope = x-0/0-y.

But if we go by conventional methods, isn't slope = rise/run i.e y2-y1 / x2-x1.

Am I missing something?
I am really confused about the slope now.
