A segment has a midpoint at ( $\"2\"$ , $\"-7\"$ ) and an endpoint at ( $\"8\"$ , $\"-5\"$ ).
\n" ); document.write( " What are the coordinates of the other endpoint?\r
\n" ); document.write( "\n" ); document.write( "Notice that the midpoints are the average of the coordinate. \r
\n" ); document.write( "\n" ); document.write( "the other endpoint ( $\"x\"$ , $\"y\"$ ) coordinates will be\r
\n" ); document.write( "\n" ); document.write( " $\"2=%288%2Bx%29%2F2\"$
\n" ); document.write( " $\"4=8%2Bx\"$
\n" ); document.write( " $\"x=-4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-7=%28-5%2By%29%2F2\"$
\n" ); document.write( " $\"-14=-5%2By\"$
\n" ); document.write( " $\"-14%2B5=y\"$
\n" ); document.write( " $\"-9=y\"$ \r
\n" ); document.write( "\n" ); document.write( "the other endpoint is at ( $\"x\"$ , $\"y\"$ )=( $\"-4\"$ , $\"-9\"$ )\r
