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 plug in the $x$ and $y$ values in the given coordinates: $m=\frac{2-(-2)}{-3-(-3)}$
We simplify above and below the fraction bar with subtraction: $m=\frac{4}{0}$
Since any number divided by $0$ is undefined, the slope of this line is undefined.
