Answer:

Graph 2

Step-by-step explanation:

Graph two is not a function because it does not pass "the vertical line test", which is a method of determining if a graph is a function or not. To do this, we use our pen to check that for every x value there is only one y value. In graph two, however, this is not the case.

So since each pack has 6 packs we need to multiple. 6x8= 48.

There were 48 diet sodas in the cooler. 40 were drank. The fraction would be 40/48 were drank or 8/48 cans were not drunk.

For the lowest term, it would be 1/6 for 8/48 and 5/24 for 40/48.

Good luck with your studies! <3
