You can put this solution on YOUR website!
Remember for point x_1,y_1 and x_2,y_2 we have that M(x,y) = (x_1+x_2)/2 , (y_1+y_2)/2
For notation let M_x be the midpoint's x coordinate and similarly let M_y be the midpoint's y coordinate.
Then M_x = (x_1+x_2)/2 and M_y = (y_1+y_2)/2.
This should be sufficient to solve.
