Help asap please the midpoint of AB is M (1, 3). if the coordinates of A are (4, 1), what are the coordinates of B?

I believe it would be (-2,5), since the x coordinate for A decreased by 3 and the y coordinate for A increased by 2. You would take the x coordinate of M and subtract 3 which would be 1-3=-2 and then take the y coordinate of M and add 2 which would be 3+2=5. So the coordinates for B would be (-2,5)
