Answer: (6, -6)

Step-by-step explanation:

so midpoint =(\frac{X1+X2}{2},\frac{Y1+Y2}{2})

for x co ordinate

\frac{-2+X2}{2}=2

-2+X=4            (X2=x co ordinate point for b, can be written as just x now)

X=6

x co ordinate of B= 6

y co ordinates of y

\frac{-8+Y2}{2}=-7

-8+Y=-14

Y=-6

co ordinates B (6,-6)

for proof/extra explanation (NOT necessary for working):

\frac{Y1+Y2}{2}

=\frac{(-2)+6, (-8)+(-6)}{2}

=\frac{4, -14}{2}

=(2,-7)

which is the midpoint M
