I think that equation is supposed to look like this:

The reason I say that is because this is an exponential decay problem, with a starting amount of 50 pieces of candy.
If that's the case, then it would look like this with a t value of 5:

and

so the amount of candy left after 5 minutes is 16.384 or 16
The slope is rise over run
The rise is 1
The run is 2
So the slope would be 1/2
