Answer:
Explanation:
When you graph a proportional relationship, the line goes through the
origin, (0, 0). At that point, the "a" and "b" are both equal to 0.
0/0 is not constant. It's not even defined.
This is true so from the pair (0, 0), you can't determine that constant. This matches up with the fact that 0/0 is indeterminate, and therefore undefined.
