\"8x-9y%2B2=0\" --> \"8x%2B2=9y\" --> \"8x%2F9%2B2%2F9=y\" or \"y=%288%2F9%29x%2B2%2F9\"
\n" ); document.write( "The slope of the given line is \"8%2F9\".
\n" ); document.write( "A perpendicular line will have a slope of \"-9%2F8\"
\n" ); document.write( "Setting up an equation such as \"-9=-7%28-9%2F8%29%2Bb\" and solving for b would work.
\n" ); document.write( "\"-9=-7%28-9%2F8%29%2Bb\" --> \"-9=63%2F8%2Bb\" --> \"b=%28-63%2F8%29-9\" --> \"b=-63%2F8-72%2F8\" --> \"b=-135%2F8\"
\n" ); document.write( "Otherwise, the point slope form of the equation is
\n" ); document.write( "\"y-%28-9%29%29=%28-9%2F8%29%28x-%28-7%29%29\" --> \"y%2B9=%28-9%2F8%29%28x%2B7%29\" --> \"y%2B9=%28-9%2F8%29x%2B7%28-9%2F8%29\" --> \"y%2B9=%28-9%2F8%29x-63%2F8\" --> \"y=%28-9%2F8%29x-63%2F8-9\" --> \"y=%28-9%2F8%29x-63%2F8-72%2F8\" --> \"y=%28-9%2F8%29x-135%2F8\"
