Answer:

Gift card

Explanation:

Given

Function 1 and 2

Required

Which has a negative slope

For the first function (Gift card), we have the following observation.

As x increases from 0, 1, 2 and then 3

The values of y keep reducing

This means that the gift card function has a negative slope

For the second function (calculator rental)

We have:


c = 10 + 5m

The slope of function
y =mx + b is m

So, by comparison


m=5

5 is positive,

This means that the gift card function has a negative slope
