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 y-intercept of the graph represents the initial value of the dependent variable when the independent variable is zero. In this scenario, the y-axis represents the altitude of the hot air balloon in feet, and the x-axis represents time in minutes.
Since the y-intercept is at 600 feet, this means that at time zero (when the descent begins), the hot air balloon starts at an altitude of 600 feet.
Therefore, the correct response is:
The balloon starts its descent at 600 feet.
