Question

A. a total cost of 11.74 per month when one song is downloadedB. The cost to download 100 songs C. The base cost of the streaming service per month D. How much the streaming service chargers per downloaded song.

Answer 1

For any linear function

`y=mx+b`

The slope "m" represents the change of y every time x increases one unit.

In this case, the variable in the x-axis is "the number of songs" and the variable is the y-axis is the "total cost per month"

The slope of the line represents the increase in the service cost every time a new song is downloaded.

The correct option is D. How much does the streaming service charge per downloaded song.
