Steps

Step 1 :Suppose that the point $(x, y)$ is in the indicated quadrant N (or the first quadrant).

Step 2 :Recall that $r=\sqrt{x^{2}+y^{2}}$ and is always positive.

Step 3 :In quadrant N, both $x$ and $y$ are positive.

Step 4 :Therefore, the sign of the ratio $\frac{r}{x}$ will depend on the sign of $x$.

Step 5 :Since $x$ is positive in quadrant N, the ratio $\frac{r}{x}$ will be positive.

Step 6 :\(\boxed{\text{Final Answer: Positive}}\)
