The graph shows a line of best fit for data collected on the amount customers spent on a file sharing service in relation to the amount they uploaded. The equation for the line of best fit is shown below.

What does the y-intercept represent?
A. the cost to upload an unlimited amount of files

B. the cost to enroll in the file sharing service

C. the cost per file uploaded

D. the cost per Mb uploaded

faster, im not sure why but i know it is faster

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
