I think urmila meant to post it here, but sent it to me in a private message instead.
I think the answer is B.
I guess if both lines have to pass through the point(1,1) and line L has a negative slope implies line K must have a positive slope. However, slope of line L will be higher than that of line K and even in any case the Y-intercept made by line L will be greater than that made by line K.
Please let me know whether I am correct or wrong.
i disagree Urmila
K can be both positive and negative.
L = -5 , K = 5 , K= -3 OR K= -10
thats why B is insufficient
