a.
Explanation of Solution
Given information:
No of songs (in million) =500
Year= 2006
No of songs (in million) =200
Year= 2004
Graph:
Thegraph is:
Interpretation:
The y -axis is labelled as years and x -axis is labelled as songs (in millions)
b.
To find the slope of the graph
b.
Answer to Problem 2CYP
Slope is 150.
Explanation of Solution
Given information:
No of songs (in million) =500
Year= 2006
No of songs (in million) =200
Year= 2004
Calculation:
To represent the equation,
Let coordinates be
So,
Where,
Solving,
So,
Hence, slope is 150.
c.
To find number of songs to be downloaded in 2010.
c.
Answer to Problem 2CYP
1100 million songs will be downloaded by 2010.
Explanation of Solution
Given information:
No of songs (in million) =500
Year= 2006
No of songs (in million) =200
Year= 2004
Observing the graph, number of songs can be calculate by observing the value of y at 2010.
So, value of y at 2010 is 1100,
So,
1100 million songs will be downloaded by 2010.
