\n" ); document.write( "\n" ); document.write( "12 x -9 y = 135
\n" ); document.write( "
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "9 y = -12 x + 135
\n" ); document.write( "Divide by 9
\n" ); document.write( " y = -4/3 x + 15
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -4/3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal =3/4
\n" ); document.write( "
