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?

The correct response is:
The balloon starts its descent at 600 feet.
In the context of a graph that models the descent of a hot air balloon, the y-intercept represents the initial height of the balloon when time (x-axis) is zero. Since the intercept on the y-axis is at 600 feet, it indicates that the balloon starts its descent from that height.
