First find the slope.
\n" ); document.write( "\"8x-6y=-13\"
\n" ); document.write( "\"6y=8x%2B13\"
\n" ); document.write( "\"y=%284%2F3%29x%2B13%2F6\"
\n" ); document.write( "The slope of this line is \"m1=4%2F3\"
\n" ); document.write( "Perpendicular lines have slopes that are negative reciprocals,
\n" ); document.write( "\"m1%2Am2=-1\"
\n" ); document.write( "\"%284%2F3%29%2Am2=-1\"
\n" ); document.write( "\"m2=-3%2F4\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"y=-%283%2F4%29x%2Bb\"
\n" ); document.write( "Use the point, (-4,5), to solve for \"b\".
\n" ); document.write( "\"5=-%283%2F4%29%28-4%29%2Bb\"
\n" ); document.write( "\"b%2B3=5\"
\n" ); document.write( "\"b=2\"
