Use thia formula to find the midpoints of segments with these endpoints.
\n" ); document.write( "a. (-4,3) and (6,-9)
\n" ); document.write( "x: (-4+6)/2 = 1
\n" ); document.write( "Y: (3-9)/2 = -3
\n" ); document.write( "--> (1,-3)
\n" ); document.write( "---------
\n" ); document.write( "Do the others the same way.
\n" ); document.write( "b. (-4,0) and (4,0)
\n" ); document.write( "c. (-2,1) and (4,3)
\n" ); document.write( "d. (-4,3) and (4,-3
\n" ); document.write( "
\n" );
