You can put this solution on YOUR website!
x is propotional to y^2
\n" ); document.write( "x=k y^2,k is a constant
\n" ); document.write( "when y=3,x=6 6=(3^2)k
\n" ); document.write( " k=6/9=2/3
\n" ); document.write( "the equation is x=2(y^2)/3
\n" ); document.write( "when y=6 x=2(6^2)/3
\n" ); document.write( " x=2(36)/3
\n" ); document.write( " x=24\r
\n" ); document.write( "\n" ); document.write( "so answere is (E)24
\n" ); document.write( "
\n" );
