Answer:
Please review the question. I don't see a diagram. And the "expressions" are just numbers.
Explanation:
The expressions aren't really expressions. There are no variables (x or y).
-6 - (-1) is -5
-6 - 1 is -7
-5 - (-1) is -4
-5 -1 is -6
We don't know if these are values of x or y, so the diagram could only be a series of dots on a number line.
