Question

M is the midpoint of AB¯. Find the coordinates of B given A(–2, 1) and M(4, 3).

Answer 1

B(10,5)

Explanation:

You already have A and M so you just find the difference and add it to M. That is my way of getting the answer. I am taking the Honors Geometry class in 6th grade.

Answer 2

B (10, 5)

Explanation:

We simply set the midpoint equal to each of its respective variable equation in
`m = ((x1+x2)/(2),(y1+y2)/(2) )`

Step 1: Solve x

4 = (-2 + x)/2

8 = -2 + x

x = 10

Step 2: Solve y

3 = (1 + y)/2

6 = 1 + y

y = 5

Put it in coordinates and we have our final answer!
