Without the specific graph to refer to, I can provide guidance on how to determine which situation might be modeled by Line C based on the nature of its slope and behavior.
- If Line C is a straight diagonal line sloping downward, it likely represents a situation where an object is moving at a constant rate (like the bicyclist or hot-air balloon).
- If Line C has a steep slope that becomes less steep over time, it may suggest acceleration (like the boulder rolling downhill).
- If Line C starts steep and becomes less steep in a negative direction, that could indicate a decrease in speed (like the car slowing down).
To choose the correct answer, identify the characteristics of Line C from the graph you have and match it to these descriptions. If Line C is not changing in steepness (constant slope), it would suggest constant speed, which aligns with scenarios involving the bicyclist or hot-air balloon. If Line C is a straight line but moves downward consistently, indicating a constant descent, that would likely be the hot-air balloon.
Based on that reasoning, if Line C is a straight diagonal line indicating a constant speed downward, the most fitting choice would typically be:
A hot-air balloon descends to the ground at a constant rate.
If you have more details about the graph, I can help refine this answer further!
