You can put this solution on YOUR website!
Sort into y = mx + c
\n" ); document.write( "-x + 5y = -6
\n" ); document.write( " 5y = x - 6
\n" ); document.write( " y = 1/5x - 6/5
\n" ); document.write( "Lines that are perpendicular
\n" ); document.write( "have gradients that multiply
\n" ); document.write( "together to give -1
\n" ); document.write( "m1 x m2 = -1
\n" ); document.write( "So, new gradient = -5
\n" ); document.write( "Using y = mx + c
\n" ); document.write( " y = -5x - 7.
\n" ); document.write( "Hope this helps
