A coordinate plane's x-axis ranges from 0 to 30 by 10-unit increments and its y-axis ranges from 0 to 600 by 200-unit increments. A diagonal line is plotted.
The graph models the descent of a hot air balloon in feet per minute. What does the y-intercept tell you in this situation?

In this context, the y-intercept of the graph represents the starting point of the balloon's descent. Since the y-axis indicates altitude in feet and the y-intercept is at 600 on this axis, it suggests that the balloon starts its descent at 600 feet.
Therefore, the correct response is:
The balloon starts its descent at 600 feet.
