I think the distance is 3/7. This is because 4 minus 1 is 3 (they are both in the same quadrant, so u subtract/are both positive too). -3 is three away from zero and 4 is 4 away from zero. If you add those together, you get those points (also, u add numbers in different quadrants together). Therefore, the distance is 3/7. Hope this helps!
