Answer to Question 1

B

Answer to Question 2

The points in the graphs relate the quantity of the variable measured on the one axis to the quantity of the variable measured on the other axis. The quantity of the variable measured on the horizontal axis (the x-axis) is measured by the horizontal distance from the origin to the point. Similarly, the quantity of the variable measured on the vertical axis (the y-axis) is measured by the vertical distance from the origin to the point. The point relates these two quantities. For instance, in Figure A1.2a, point A shows that at a price of 1.37 per song, 3.8 million songs are downloaded.
