Question
Use the image to answer the question.
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 scenario, the y-intercept represents the initial height of the hot air balloon at the moment it starts to descend (when time is 0 minutes).
Therefore, the correct interpretation of the y-intercept in this situation is:
The balloon starts its descent at 600 feet.
