Answer 1

1. Delta y means the change in y. Since the slope = m = change in y/change in x, if the change in y = 0, then 0/x = 0 (as long as the change in x is not zero)
2. If delta x = 0, then you have m = delta y/delta x, but delta x = =, so you have m = delta y/0. Division by zero is undefined.

Answer 2

So, what would the answers be?

Answer 3

I believe I just gave them to you . Read what I wrote carefully.

Answer 4

Alright, miss read it. Thanks.
