The y-intercept of a graph represents the value of the dependent variable (in this case, the height of the balloon) when the independent variable (time) is zero.
In the context of the descent of a hot air balloon, the y-intercept indicates the starting height of the balloon before it begins to descend. Therefore, the appropriate response is:
**The balloon starts its descent at 600 feet.**
