You can put this solution on YOUR website!
1. $\"y%2Fx=k\"$ where k is the constant of variation
\n" ); document.write( ":
\n" ); document.write( " $\"5%2F-1=-5\"$ --->k=-5 ---> $\"y=-5x\"$
\n" ); document.write( ":
\n" ); document.write( "2) $\"zx%2Fy=k\"$ where k is the constant of variation
\n" ); document.write( ":
\n" ); document.write( " $\"2%283%29%2F12=6%2F12=1%2F2\"$ k=1/2--->zx=(1/2)y---> $\"y=2zx\"$ \n" ); document.write( "

\n" );
