Can someone please help me?

Answer:
The other endpoint = (2, 6)
Step-by-step explanation:
( -6 , -6) and midpoint ( -2 , 0 )
1. Just looking at x-coordinate:
it goes from -6 to -2, which is an increase of 4.
The x- coordinate of the other endpoint must therefore be also 4 to the right of the midpoint.
So -2+ 4 = 2
2. Just looking at y-coordinate:
it goes from -6 to 0, which is an increase of 6.
The y- coordinate of the other endpoint must therefore be also 6 above of the midpoint.
So 0+ 6 = 6
The other endpoint = (2, 6)
