A line L1 perpendicular to the x-axis is a vertical line of the form: x = a
\n" ); document.write( "where a is the x-intercept of L1.
\n" ); document.write( "---
\n" ); document.write( "If L1 passes through the point p1 = (-1, -7) then the equation for L1 is:
\n" ); document.write( "---
\n" ); document.write( "x = -1
