You can put this solution on YOUR website!
y=kx
\n" ); document.write( ".
\n" ); document.write( "8=k*13,,,,,given (13,8)
\n" ); document.write( ".
\n" ); document.write( " 8/13 =k
\n" ); document.write( ".
\n" ); document.write( "y=8/13 * x = (8/13) * 3 = 24 /13, when x =3
\n" ); document.write( "
\n" );
