Lines L and M are in xy-plane such that neither of these is parallel to either of the axes. Is the y–intercept of the line L smaller than that of line M?

(1) Slope of line L is negative and the slope of line M is positive.

(2) Line L has a positive x–intercept.

sure!!!!!

check below attached fig. for clarification.

(1) for case 1, y intercept may be equal...insuff

(2) no info on line m...insuff

again combining both ,consider fig of case 2
where line m may be in 1st or 3rd quadrant...insuff

Ans E

Lines L and M are in xy-plane such that neither of these is parallel to either of the axes. Is the y–intercept of the line L smaller than that of line M?

Line equation of (L): y(L) =a*x(L) + b
Line equation of (M): y(M) =e*x(M) + f
According to the question: b > f?????

(1) Slope of line L is negative and the slope of line M is positive.
Slope of line L is a, and a <0
Slope of line M is e and e >0
------>We have no idea how b&f look like---->Not sufficient.

(2) Line L has a positive x–intercept.
x–intercept is -(b/a), we still have no idea how y-intercept of line (M) looks like---->Not Sufficient.

(1) +(2): We know that both e&b >0 but still no idea how it compares to each other, which one is greater than the other---> Not sufficient.
