Question

(25 POINTS) Find the coordinates of the missing endpoint if E is the midpoint of DF such that F(2,9) and

E(-1.5,6)

How do i do endpoint endpoint

Answer 1

(-5, 3)

Explanation:

The coordinates of the midpoint are the averages of the endpoints.

-1.5 = (x + 2) / 2

-3 = x + 2

x = -5

6 = (y + 9) / 2

12 = y + 9

y = 3
