To find the length of overline AB, we can use the distance formula:
√[(x2 - x1)^2 + (y2 - y1)^2]
Plugging in the coordinates of A(-4, 4) and B(2, 1):
√[(2 - (-4))^2 + (1 - 4)^2]
√[6^2 + (-3)^2]
√[36 + 9]
√45
≈ 6.7 units
Therefore, the measurement closest to the length of overline AB is option B, 6.7 units.
√[(x2 - x1)^2 + (y2 - y1)^2]

Therefore, the measurement closest to the length of overline AB is option B, 6.7 units.
