What is the slope of a line that is parallel to a vertical line?

Quincy Doyle

Determine the square root of 100.
$100=10×10$
Take the square root of the above value on both sides.
$\sqrt{100}=\sqrt{10×10}$
$\sqrt{100}=10$
Thus, the square root of 100 is 10.

Karli Foley

Keep in mind that if one line is vertical, all subsequent parallel lines are also vertical.
For any two points $\left({x}_{1},{y}_{1}\right)$ and $\left({x}_{2},{y}_{2}\right)$ on a line
the slope is defined as $\frac{{y}_{2}-{y}_{1}}{{x}_{2}-{x}_{1}}$
BUT if the line is vertical ${x}_{1}={x}_{2}$ for all points on the line
and therefore the definition of the slope would require dividing by zero (which is undefined).
