Coordinates of B is (3,-4)
You multiply -2 by 2 to get -4 and then create the equation then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
You multiply -1 by 2 to get -2 and then create the equation then you subtract 2 by -2 which gives you -4 (y coordinate of B)
To check your answer use the midpoint formula
which will give you the midpoint (-2,-1)
