Think the OA is E.

You can use the y = mx + c equation. We need C.

1. slope of the line L is 3 times its y-intercept.
y = 3cx + c.
Not sufficient to solve.

2. The x-intercept of the line L is -1/3
Which means when y=0, x = -1/3.
0=m(-1/3) + c
Which means m =3c which is just statement 1. no new info. cannot solve.

The combined also doesnot work because anyway the second statement is same as 1st stmt.

Hence E.
Vineesh,
Just telling you what I know and think. I am not the expert. :)
