Answer

$x=(+),y=(-)$ or $x=(-),y=(+)$

Work Step by Step

We are asked to find signs of $x$ and $y$ that make quotient greater than $0$. We are also told that these values are non-negative. A positive $x$ value divide by a negative $y$ value gives a negative quotient value that is less than $0$. Likewise, a negative $x$ value divided by a positive $y$ value gives a negative quotient value that is less than $0$.
