This thing is the same thing as that over there. And we were able to see that just by inspecting this graph or this chart. And then 6 minus 4, absolute value of that, that's just going to be 2. That 2 is that 2 right over here, which is the same thing as this 2 right over there. And then finally, our 1 minus 4, that's negative 3, but the absolute value of that is just positive 3, which is this positive 3 right over there, which is the distance, this distance right over here.
