G is point (-2, -3),
\n" ); document.write( "H is point (-2, 7),
\n" ); document.write( "M is point ( 4, ?)\r
\n" ); document.write( "\n" ); document.write( "Solving for the value of M(y):
\n" ); document.write( "We use the midpoint formula:(y1+y2)/2\r
\n" ); document.write( "\n" ); document.write( "Substitute the y values of point G and H
\n" ); document.write( "M(y) = (-3 + 7) /2
\n" ); document.write( "Giving us the value of M(y) = 2. (Ans.)
\n" ); document.write( "
\n" );
