$\"M=midpoint\"$ ; endpoint 1=( $\"x%5B1%5D\"$ , $\"y%5B1%5D\"$ ); endpoint 2=( $\"x%5B2%5D\"$ , $\"y%5B2%5D\"$ )
\n" ); document.write( " $\"M=%28x%5B1%5D%2Bx%5B2%5D%29%2F2\"$ , $\"%28y%5B1%5D%2By%5B2%5D%29%2F2\"$
\n" ); document.write( ".
\n" ); document.write( "x value of second point:
\n" ); document.write( " $\"x%5Bmidpoint%5D=%28x%5B1%5D%2Bx%5B2%5D%29%2F2\"$
\n" ); document.write( " $\"3=%28-2%2Bx%5B2%5D%29%2F2\"$
\n" ); document.write( " $\"6=-2%2Bx%5B2%5D\"$
\n" ); document.write( " $\"8=x%5B2%5D\"$ The x value of the second point is 8.
\n" ); document.write( ".
\n" ); document.write( "y value of second point:
\n" ); document.write( " $\"y%5Bmidpoint%5D=%28y%5B1%5D%2By%5B2%5D%29%2F2\"$
\n" ); document.write( " $\"-1=%28-7%2By%5B2%5D%29%2F2\"$
\n" ); document.write( " $\"-2=-7%2By%5B2%5D\"$
\n" ); document.write( " $\"5=y%5B2%5D\"$ The y value of the second point is 5.
\n" ); document.write( ".
\n" ); document.write( "ANSWER: The other endpoint is (8,5). \n" ); document.write( "
