identify the unit rate of the graph:

when the song is at 1, the cost is 0.99, when the songs are at 2, the cost is $1.98
Divide the cost by the number of song: 1.98 / 2 = 0.99 per song.
The unit rate is $0.99 per song.
Answer:
$0.99
Step-by-step explanation:
The unit rate is the rate of change. This is
change in y/change in x
We can see on the graph that the change in y between each point is 0.99.
The change in x between each point is 1.
This makes the unit rate
0.99/1 = 0.99.
