See a solution process below:

Explanation:

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

This means for each and every value of yy, the xx value is the same.

So, give the point (-8, 1)(8,1) we know the xx value is -88.

Therefore, we can plug any value in for yy and xx will always be -88.

Additional points are:

(-8, 2)(8,2) or

(-8, 3)(8,3) or

(-8, 4)(8,4) or

(-8, -2)(8,2) or

(-8, -3)(8,3) or

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

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

(-8, 1.2345678901234567890123456789)(8,1.2345678901234567890123456789)
