Question

perpendicular to the x-axis and passing through (8, 1)

Answer 1

y = 1 is parallel to the x-axis (y=0).

 

The question asks for a line perpendicular to the x-axis and passing through (8, 1).

 

Perpendicular to the x-axis(which is horizontal) means it's a vertical line.

 

Vertical lines are in the form x=a, and in this case, since the line must go through (8,1), the answer would be:

 

x = 8

I concur with Jason's answer.  My original response was for a line perpendicular to the y-axis.
