What is the midpoint of the line segment that has one endpoint as (11,-15) and the
\n" ); document.write( "other endpoint as (-6,9)?
\r\n" );
document.write( "First I plot the points and draw the line:\r\n" );

document.write( "\r\n" );
document.write( "Average the first coordinates, which are 11 and -6:\r\n" );
document.write( "Add them (11)+(-6) = 5\r\n" );
document.write( "Divide by 2.\r\n" );
document.write( "Get \"5%2F2\"\r\n" );
document.write( "So \"5%2F2\" is the first coordinate of the midpoint.\r\n" );
document.write( "\r\n" );
document.write( "Average the second coordinates, which are -15 and 9:\r\n" );
document.write( "Add them (-15)+(9) = -6\r\n" );
document.write( "Divide by 2.\r\n" );
document.write( "Get \"%28-6%29%2F2\", which reduces to -3\r\n" );
document.write( "So \"-3\" is the second coordinate of the midpoint.\r\n" );
document.write( "\r\n" );
document.write( "So \"%28matrix%281%2C3%2C5%2F2%2C%22%2C%22%2C-3%29%29\" is the midpoint of the\r\n" );
