If x < 0, is y > 0 ?

(1) x/y < 0. This implies that x and y have opposite signs and since given that x is negative then y must be positive. Sufficient.

(2) y - x > 0. This implies that y > x. So, y is greater than some negative number. Not sufficient to say whether y is positive. Not sufficient.

For statement 2, you can try :

Case 1: x=-5 and y=-3

Case 2, x=-5 and y=10

The above 2 cases will give you 2 different answers to make statement 2 not sufficient.
