A restaurant charges $3 for a soda and it includes free unlimited
refills. If this situation were represented as a function, what would be
the slope?

1)O
2)3
3)5
4)7

The answer is zero
For each soda you would be the price would go up
The slope is that price that you buy the soda
Except since it is unlimited it means we don’t have to pay for the soda each time we buy one
So every time we buy a soda the price we pay for is not existent
I hope this helps
