The y-intercept of a graph represents the point where the line crosses the y-axis. In the context of a graph that models the descent of a hot air balloon in feet per minute, the y-intercept would typically represent the starting height of the balloon when the descent begins, assuming the time (x-axis) starts from zero.
Therefore, the correct answer for what the y-intercept tells you in this situation would be:
B. The balloon starts its descent at 600 feet.
This means that at time zero (before any descent), the hot air balloon is at an altitude of 600 feet.
The graph models the decent of a hot air balloon in feet per minute. What does the y-intercept tell you in this situation?
A. The balloon rises 600 feet.
B. The balloon starts its decent at 600 feet.
C. The balloon takes 0 minutes to descend 600 feet.
D. It will take the balloon 600 minutes to descend.
