Given the coordinate of one endpoint of segment AB and its midpoint M, find the coordinates of the other endpoint.
\n" ); document.write( "A(0,9), M(2,5)\r
\n" ); document.write( "\n" ); document.write( "-----------------------
\n" ); document.write( "Let the other end point be (x,y)
\n" ); document.write( "-----------------
\n" ); document.write( "The midpoint coordinates are the average of the corresponding
\n" ); document.write( "end point coordinates.
\n" ); document.write( "-----------------------
\n" ); document.write( "(x+0)/2 = 2
\n" ); document.write( "x = 4
\n" ); document.write( "----
\n" ); document.write( "(y+9)/2 = 5
\n" ); document.write( "y+9 = 10
\n" ); document.write( "y = 1
\n" ); document.write( "-----------------
\n" ); document.write( "The other end point is (4,1)
