#### Answer

The slope is undefined, which means that the line is vertical line.
Refer to the graph below.

#### Work Step by Step

The slope of the line can be determined by the equation:
$m=\dfrac{y_2-y_1}{x_2-x_1}$
where $(x_1, y_1)$ and $(x_2, y_2)$ are two given points on the line.
Here, we can substitute the coordiantes of the points $(2,0)$ and $(2,2)$ to obtain:
$m=\dfrac{2-0}{2-2)}=\dfrac{2}{0}$ which is undefined.
This means that the line is vertical.
Plot the points and connect them using a line.
