Answer: 4.
Step-by-step explanation: In this case it is easier to imagine it on the number line: the y coordinates are the same, so the distance is only in x direction. On the positive side it is 2 2/3 to zero and on the negative, 1 1/3 to zero. Total is 1 1/3 + 2 2/3 = 4. Or the proper writing: 2 2/3 - (-1 1/3) = 4
