\n" ); document.write( "\n" ); document.write( "A line parallel to the

-axis is a vertical line. Vertical lines have a couple of interesting characteristics. In the first place, ALL of the

-coordinates of the set of ordered pairs that comprise the line have to be identical. Since all of the

-coordinates are equal, no matter which two points you choose for the purposes of computing the slope, the slope fraction will have a zero denominator. Hence, the slope of any vertical line is undefined.\r

\n" ); document.write( "\n" ); document.write( "You can't write the equation of a vertical line in slope-intercept form because the slope quantity is undefined. However, since the

-coordinates of all the points on the line are identical, the equation of a vertical line passing through the point

is uniquely defined by the equation
