Point a is located at (2, 6), and point m is located at (−1, 8). if point m is the midpoint of segment ab, find the location of point b.

(5, 4)
(0.5, 7)
(0, 6)
(−4, 10)

  (−4, 10)

Step-by-step explanation:

If M is the midpoint of AB, then ...

  M = (A + B)/2

  2M = A + B . . . . . . multiply by 2

  2M -A = B . . . . . . . subtract A

  2(-1, 8) -(2, 6) = (-2-2, 16-6) = (-4, 10)

It can be worthwhile to remember how to get the endpoint from the other end and the midpoint: B = 2M - A.

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
