A line perpendicular to the -axis is a vertical line. A vertical line through a given point has the property that ALL ordered pairs that comprise the line have identical -coordinates, and the -coordinates comprise the set of real numbers. Therefore, the only restriction on any given pair in the line you wish to describe is that . That equation fully and uniquely describes the line you seek and is, in fact, the equation you want.
