If M(-2,9) is the midpoint of segment PQ and the coordinates of P are (-7,7) find the coordinates of Q?

Question

select the answer

(-4.5,8)

(-11,25)

(2.5,1)

(3,11)

Answer 1

x is (P = -7), (M = -2), (Q = 3)

y is (P = 7), (M = 9), (Q = 11)

Answer:  (3,11)

This question does not belong in GEOGRAPHY.

Answer 2

(3, 11)

The x-coordinate of the midpont is 5 units to the right of the x-coordinate of P (-2-(-7)=5).  The x-coordinate of Q is going to be 5 units to the right of the x-coordinate of M: -2+5=3

The y-coordinate of the midpont is 2 units above the y-coordinate of P (9-7=2).  The y-coordinate of Q is going to be 2 units above the y-coordinate of M: 7+2=11
