Answer:
(0, 1) is the midpoint of K.
Explanation:
Let's reverse the order of motion and go from E to W. Then it becomes more obvious that the change in x here is (4 - [-4]), or 8, and the change in y is (3 - [-3]), or 6.
The midpoint of the line segment representing the change in x is 8/2, or 4.
That of the segment representing the change in y is 6/2, or 3.
Adding 4 (found above) to -4 (x-coordinate of vertex E) yields 0. The midpoint of the x-component of location of K is x = 0.
Adding 3 (found above) to -1 yields 1. The midpoint of the y-component of K is y = 1.
Thus the coordinates of K are (0, 1)
