given: \r
\n" ); document.write( "\n" ); document.write( "find the line passing through ( $\"2\"$ , $\"2\"$ ) and perpendicular to $\"x=-9\"$ \r
\n" ); document.write( "\n" ); document.write( "The line $\"x=-9\"$ is a $\"vertical\"$ line. Because it is vertical, its slope $\"m\"$ is $\"undefined\"$ .\r
\n" ); document.write( "\n" ); document.write( "Since we have a vertical line of $\"x=-9\"$ , we need something $\"perpendicular\"$ to it (a horizontal line) passing through ( $\"2\"$ , $\"2\"$ ). so, we can use $\"y=2\"$ ;it a horizontal line and is perpendicular to the vertical line, and it runs through the point ( $\"2\"$ , $\"2\"$ )\r
