Question

The graph below shows the fine that a college student pays to the library based on the number of minutes a loaner laptop is overdue:

A graph is shown. The values on the x axis are 0, 2, 4, 6, 8. The values on the y axis are 0, 0.70, 1.40, 2.10, 2.80. Points are shown on ordered pairs 0, 0 and 2, 0.70 and 4, 1.40 and 6, 2.10. These points are joined by a line. The label on the x axis is Minutes Overdue. The title on the y axis is Fine.

Which statement best describes the point (0, 0) on the graph?

Answer 1

So the answer would be No fine is paid if the laptop is returned exactly at the time at which it is due

Answer 2

Create a Cartesian plane with the x and y axes. Then, plot the given points on the plane: (0,0), (2,0.7), (4,1.4), (6,2.1). Lastly, connect these 4 data points to form a line. The x-axis represents minutes overdue and the y-axis represents the fine. The result is shown in the picture.

This graph shows an increasing linear trend. It shows that the fine is directly proportional with time. At time 0 minutes, the college student does not have to pay a fine because he hasn't even used the laptop yet. Therefore, the origin (0,0) signifies the starting point of the observation. But when he used 2 minutes of the time, he would pay $0.7. The trend goes on until he used up 6 minutes and paid a total of $2.1
