Midpoint Formula
Point A is at (-2,-4) and point M is at (2.5,3.5)
Point M is the midpoint of point A and point B
What are the coordinate points of B

Answer 1

• Point B has coordinates of (7, 11)

=========================

The midpoint has average value of coordinates of endpoints.

It gives us the following equations:

• ( - 2 + x)/2 = 2.5
• - 2 + x = 5
• x = 5 + 2
• x = 7

and

• (- 4 + y)/2 = 3.5
• - 4 + y = 7
• y = 7 + 4
• y = 11

Point B is (7, 11).
