Question

M is the midpoint of sq AB Co-ordinate al point A and M are
(-3,7) and (5,-1) Find to coordinate of point B​

Answer 1

Answer:

$coordinates \: of \: b(13 \: \: \: \: \: \: - 9)$

Step-by-step explanation:

$( \frac{x - 3}{2} \: \: \: \: \frac{y + 7}{2} ) = (5 \: \: \: \: \: - 1) \\ \\ x - 3 = 10 \: \: \: \: \: \: y + 7 = - 2 \\ x = 13 \: \: \: \: \: \\ y = - 9 \\ \\ \\ coordinates \: of \: b(13 \: \: \: \: \: \: - 9)$
