document.write( "\r\n" );
document.write( "Pretend that the point is a baseball and the y-axis is a mirror, and\r\n" );
document.write( "you look into the mirror, where will you see the reflection of the\r\n" );
document.write( "baseball?  It will be on the left of the y-axis, the same distance\r\n" );
document.write( "from the y-axis:\r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
document.write( "\r\n" );
document.write( "So the image of (2,3) after a reflection over the y-axis is (-2,3).\r\n" );

document.write( "Three kinds of reflections are over the y-axis, x-axis, and the origin.\r\n" );
