ANSWER

EXPLANATION
The given identity is

We expand the numerator to get:

Split the numerator to obtain:

Cancel the common factors:

This simplifies to give us;

The second choice is correct
Answer:
(0,1)
Step-by-step explanation:
Coordinates of midpoints equal to half of total of 2 endpoints
xK = (xW + xE)/2 = (4 + -4)/2 = 0/2 = 0
yK = (yW + yE)/2 = (3 + -1)/2 = 2/2 = 1
so coordinate of K is (0,1)
