Question

Point A (-3,-5) and point M is at (-1,-7) what are the coordinates point of be

point M is the midpoint off point A and point B

Answer 1

the answer is b

Explanation:

Answer 2

Answer: B = (1,-9)

Explanation:

`x_M=(x_A+x_B)/(2) \\\\y_M=(y_A+y_B)/(2) \\\\\\x_B = 2x_M-x_A=2(-1)-(-3)=1\\\\y_B = 2y_M-y_A=2(-7)-(-5)=-9\\`
