To create:the graph to show how the number of song downloaded and remaining balanced are related.

Explanation of Solution
Given:
The given function table shows the balance on a $50 music card after a certain number of songs have been downloaded.
Calculation:
According to the table, draw the graph of ordered pair.
Now, draw the graph to show how the number of song downloaded and remaining balanced are related by using the given coordinates in the table:
As the songs are downloaded at 5, the remaining balance is also decreased by 5. Its relationship is linear.
