In the rectangular co-ordinate system, does the line k(not shown) intersect Quadrant II??

(1) The slope of k is -1/6

(2) The y intercept of k is -6

Ans A

The negative slope indicates that the line slopes downward from left to right.

So i guess this is sufficient to indicate that, the line intersect the quadrant II.
But not very sure !! Any expert's suggestion !!

yup,

A negative slope can never intersect the II Quadrant.

I is sifficient alone.

Still not sure about it..Is there any other way this problem can be solved??

(A) is sufficient because it WILL eventually go through quadrant II.
