A graph shows a horizontal axis representing time in months ranging from 0 to 10 in increments of 1. The vertical axis represents cost of music subscription ranging from 0 to 20 in increments of 2. Two plotted points are: left parenthesis 0 comma 10 right parenthesis, left parenthesis 1 comma 12 right parenthesis. These points are joined by a straight line with arrows on both the ends.

The y-intercept of a graph represents the value of the dependent variable (in this case, the cost of the music subscription) when the independent variable (time in months) is zero. In this situation, the y-intercept is at the point (0, 10), which indicates that the initial cost of the music subscription is $10 when no time has passed (at month 0).
Therefore, the correct interpretation of the y-intercept in the context of this situation is:
The initial cost is $10 for the subscription.
