#### Answer

The slope of the line is undefined, which means the line is vertical.
See the graph below.

#### Work Step by Step

The slope of the line that passes throught two points $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the formula:
$m=\dfrac{y_2-y_1}{x_2-x_1}$
Thus, the slope of the line passing through the two given points is:
$m=\dfrac{-2-2}{-1-(-1)}=\dfrac{-4}{0} \text{ (undefiend)}$, therefore the line is vertical.
To graph, plot both points then connect them using a straight line.
Refer to the graph above.
