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.
The y-intercept of the graph represents the initial value of the dependent variable when the independent variable (time in minutes) is zero. In this context, it indicates that the balloon starts its descent at 600 feet above the ground.
