The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints. The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.
x-coordinate of midpoint: (-4 + 0)/2 = -4/2 = -2
y-coordinate of midpoint: (9 + 7)/2 = 16/2 = 8
Answer: The midpoint is (-2, 8).
