Answer
The slope is undefined.
Work Step by Step
To find the slope, we use the formula:
$$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$$
We now plug in points we find on the graph of the line into this equation to find the slope of this line. We will use the points $(-2, 3)$ and $(-2, -3)$:
$$m = \frac{-3 -3}{-2 - (-2)}$$
Simplify:
$$m = \frac{-6}{0}$$
We cannot divide by zero; the fraction is undefined. Therefore, the slope is undefined.
