Question

P(4, 8), Q(?,?), m(2,8)
FIND THE MIDPOINT CALCULATE THE MISSING CORDINATE

Answer 1

what is the midpoint formula?

Answer 2

midpoint = \[((x_1+x_2)/2, (y_1+y_2)/2)\] then \[((4+x_2)/2, (8+y_2)/2) = (2,8)\] which implies that \[(4+x_2, 8+y_2)=(4,16)\] by multiplying 2 in both sides which finishes with \[(x_2, y_2) = (0,8)\] by subtracting each component.
