The graph above shows the cost of joining and buying music from a music subsciption service. What does the y-intercept of the line most likely represent ?

Options

A. The cost per song
B. The cost to join the service
C. The cost of buying 20 sings
D. The cost of 20 subscriptions to the service

Answer

B

Explanation

Read the axis labels carefully. The y-intercept is the point at which `x =0,` which means the number of songs purchased is 0. The y-intercept is `(0,20),` so the cost is `$20` before buying any songs and therefore most likely represents a flay membership fee for joining the service. (B) is correct.
