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 from the given coordinate pairs: $m=\frac{\frac{7}{13}-\frac{2}{11}}{-2-(-2)}$ We simplify below the fraction bar with subtraction: $m=\frac{\frac{7}{13}-\frac{2}{11}}{0}$ Since any number divided by $0$ is undefined, the slope of this line is undefined.
