Point M is the midpoint of AB. The coordinates of point A are (-7, 3) and the coordinates for M are (-3, 3). What are the coordinates of point B?PLEASE HELP ITS DUE TOMORROW!!!!!!

Answer:    the coordinates of point B are :   xB = 1 and   yB = 3Step-by-step explanation:the coordinates of M are :  xM       = (xA +xB )/2                                               yM  = (yA +yB )/2 since :   xM = -3   and    yM = 3               xA = -7  and    yA = 3so :   -3 = (-7 +xB )/2            3  = (3 +yB )/2   -6 = -7 +xB6= 3 +yBxB = 1 and   yB = 3
