From the table we can see:
Number of songs: Cost:
0 $ 0
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Therefore the rate of change is: (2.50 - 1.25) / ( 2 - 1 ) = $1.25
Answer:
It means that : C. The cost increases $1.25 for each additional song that is downloaded.
Average= f(2)−f(0)/2−0

The solutions to system of equations are the point of intersection of the graphs of the equations.
The point of intersection of the graphs of the given equation is (0, 2). Therefore, point (1, 1) is not a solution to the system of equation.
