segment ab has endpoint A(-5,-4) and the midpoint M(2,0). What is the y-coordinate of point B?
\n" ); document.write( "--------
\n" ); document.write( "Let the coordinate form of B be (x,y).
\n" ); document.write( "Solve for x and for y::
\n" ); document.write( "(x-5)/2 = 2
\n" ); document.write( "(y-4)/2 = 0
\n" ); document.write( "-----
\n" ); document.write( "x = 4+5 = 9
\n" ); document.write( "y = 0+4 = 4
\n" ); document.write( "------
\n" ); document.write( "(x,y) = (9,4)
