(2) Line K crosses the x-axis at x=1.



1) Tells us co ordinates of A which is still not sufficient to determine its position and also nothing about K. INSUFFICIENT
2) Tells us that line k crosses from x= 1 . now it could be a vertical or a horizontal line apart from other n ways it could be drawn. tells us nothing about A. INSUFFICIENT.


Combine both As known from statement 1 no fixed position of A so it can be either to right or left of vertical line k ( 1 case out of n possibilities). INSUFFICIENT.

from 1, we just get to know that the point A is in region 4

from 2, we just get to know that the x axis crosses the x axis at x=1, we dont know that the slope is a +ive one or a -ive one

Now when we combine both the statements, we cannot say anything about this

Answer E
