In the xy plane, both line L and K pass through point (3, 3). Is the yintercept of line K greater than the yintercept of line L? (1) Slope of line L is positive (2) Slope of line K is less than slope of Line L According to me the answer should be but I am not very sure.Sorry I dont have the answer.

I think the answer should be C  as if the like L has the positive slope and the line k has the slope less than slope of the line L  than in that case Line K will always intersect the Y axis above Line L  Keeping in mind they both have to intersect on point (3,3).
Correct me if I am missing on something.

Nikhil nikhil, Even I think so. But we might be wrong.

You are correct that the answer is E. IMO B line L:\(Y = MX+C\) line k:\(Y = NX + D\) both are passing from \((3,3)\) therefore :\(3M+C=3N+D\) \(3(MN) = DC\) now statement 2 :\(M>N\) THREFORE \(DC > 0\) hence SUFFICIENT

Consider the line L Y=mx+b For line K y=nx+c Both the line passes through Point (3,3) hence 3m+b=3n+c 3(mn)=cb is c>b? 1) Slope of line L is positive does not give any details of n so insufficent 2) m<n mn<0 => apply this in question so o>cb c>b Statement 2 is sufficient Answer is B

Nikhil nikhil, Even I think so. But we might be wrong. Folks  Line K has slope less than line C's Slope. What if slope of K is negative ?? In that case, Y intercept may or may not be greater. Hence both the conditin together is not sufficient. Hence IMO it has to be E.

I would like to solve it by the understanding the relative position of line in the plane.
+ve slope means line is making an angle < 90 degree with Xaxis on the left hand side. Greater the slope greater the angle, while keeping the angle < 90 with x  axis on left hand side. With 90 degree angle with x axis , slope become undefined. thus, greater the angle, lower the value of Y intercept. Keep in mind both the lines pass through the same point (3,3)
Stmt 1: Slope of line L is positive This does not say anything about the slope of like k. 1. Slope of line K could be +ve , but less than that of line L, thus in this case, y intercept of line K would be higher. 2. If slope of line K > slope of line L, then y intercept of line K would be lower. Thus,Insufficient.
(2) Slope of line K is less than slope of Line L This is point 2 mentioned under choice 1 above. Thus, we can say that y intercept of line K would be higher. Thus, Sufficient.
Thus, Answer should be B.

If they have different slopes (inclination), then they must have different y interceptors (where they intercept the y axis) I think B is sufficient.

What if L has negative slope and K has positive slope.In above we have taken both L and K as positive slope.The answer will not change??

(since slope K < slope L)HOPE it helps
