See a solution process below:

A line is a vertical line when the slope of the line is undefined.

This means for each and every value of $y$ , the $x$ value is the same.

So, give the point $(-8, 1)$ we know the $x$ value is $-8$ .

Therefore, we can plug any value in for $y$ and $x$ will always be $-8$ .

Additional points are:

$(-8, 2)$ or

$(-8, 3)$ or

$(-8, 4)$ or

$(-8, -2)$ or

$(-8, -3)$ or

$(-8, 1,000,000,000,000,000,000,000)$ or

$(-8, -1,000,000,000,000,000,000,000)$ or

$(-8, 1.2345678901234567890123456789)$
