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)#
