To find the slope between two points, we use the formula:

$$m = \frac{\Delta y}{\Delta x}$$

where $\Delta y$ is the change in $y$ (vertical distance) and $\Delta x$ is the change in $x$ (horizontal distance) between the two points.

In this case, both points have the same $y$-coordinate of $-5$, so there is no change in $y$. Thus, $\Delta y = 0$. The change in $x$ is $9 - 7 = 2$.

Plugging these values into the slope formula gives:

$$m = \frac{0}{2} = 0$$

So the slope of the line passing through the given points is 0. Therefore, the correct choice is A).
