An audio books club charges an initial joining fee of $20.00. the cost per audio book is $15.00. the graph shows the cost of belonging to the club as a function of audio books purchased. how will the graph change if the cost per audio book goes up by $1.00?
(the new function is shown by the dotted line.)

The new function will have a steeper slope

Step-by-step explanation:

Let

x ----> the number of audio books purchased

y ---->the cost of belonging to the club in dollars

we know that

case 1 (Originally)

----> equation A

case 2 ( the cost per audio book goes up by $1.00)

The new equation is

The slope of the new function is greater than the slope of the original function    

The new function will have a steeper slope

The graph in the attached figure
