Answer:
Gift card
Step-by-step 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:
[tex]c = 10 + 5m[/tex]
The slope of function [tex]y =mx + b[/tex] is m
So, by comparison
[tex]m=5[/tex]
5 is positive,
This means that the gift card function has a negative slope
