The perpendicular line:
\n" ); document.write( "\"y=-%281%2F4%29x%2Bb\"
\n" ); document.write( "\"b=2-%28-1%2F4%29%2A8\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For parallel, the slopes of the lines are equal. For perpendicular, one slope is negative reciprocal of the other slope.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Slope-Intercept Form,
\n" ); document.write( "\"y=mx%2Bb\"
\n" ); document.write( "\"y-mx=b\"
\n" ); document.write( "\"b=y-mx\"------solved for b, the y-intercept
\n" ); document.write( "
\n" );
