Question 1 (1 point) Point M is the midpoint of AB. The coordinates of point A are (-6, 3) and the coordinates of M are (-1, 1). What are the coordinates of point B, the missing endpoint? Don't forget paranthesis! ()

Answer:

The answer to your question is:  (4, -1)

Step-by-step explanation:

M = midpoint   (-1, 1)

A = (-6, 3)

B = (x, y)

[tex]xm = \frac{x1 + x }{2}[/tex]

x = 2xm - x1

x = 2(-1) + 6

x = -2 + 6

x = 4

[tex]ym = \frac{y1 + y }{2}[/tex]

y = 2ym - y1

y = 2(1) - 3

y = 2 - 3

y = -1
