\n" );
document.write( "Hi
\n" );
document.write( "Decide whether the pair of lines is parallel, perpendicular or neither.
\n" );
document.write( "5x-6y=19    OR  y = (5/6)x - 19/6     | m = 5/6
\n" );
document.write( "6x+5y=-30   OR  y = (-6/5)x -6        | m = -6/5
\n" );
document.write( "Lines are perpendicular as  5/6*-6/5 = -1
\n" );
document.write( " \n" );
document.write( "
