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.
