\n" ); document.write( "\n" ); document.write( "The equation $\"x=-2\"$ represents a $\"vertical\"$ line which crosses the $\"x\"$ -axis at the point ( $\"-2\"$ , $\"0\"$ ) . Every ordered pair with $\"-2\"$ as its first coordinate is a solution . \r
\n" ); document.write( "\n" ); document.write( "so, points are:
\n" ); document.write( "( $\"-2\"$ , $\"1\"$ )
\n" ); document.write( "( $\"-2\"$ , $\"-1\"$ )\r
\n" ); document.write( "\n" ); document.write( "A vertical line has $\"undefined\"$ slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of $\"+0\"$ , which makes the slope undefined. \n" ); document.write( "
