solution:\r
\n" ); document.write( "\n" ); document.write( "(\"a\",\"b\") is reflected over the y -axis to the point at ( \"j\" , \"k\" )\r
\n" ); document.write( "\n" ); document.write( "so, (\"+j\" ,\"+k+\") = (\"-a\", \"b\") \r
\n" ); document.write( "\n" ); document.write( "\"a%2Bj=+%28a%2B%28-a%29%29=a-a+=0\"\r
\n" ); document.write( "\n" ); document.write( "\"+b%2Bk=b%2Bb=2b=0\",=> \"b=0\"
\n" ); document.write( "
\n" );
