Question

Which of these correctly describes the meaning of the y-intercept of the graph?

A.
The helicopter ends its journey 525 miles away from the airport.

B.
The helicopter takes 3.75 hours to travel to its final destination at the airport.

C.
The helicopter begins its journey 525 miles away from the airport.

D.
The helicopter takes 3.75 hours to travel to its final destination away from the airport.

Answer 1

To determine which option correctly describes the meaning of the y-intercept of the graph, we need to clarify what the y-intercept represents in a given context. The y-intercept is the point where the graph intersects the y-axis, which typically represents the initial value or starting condition of the situation being modeled.

In this context:

- If the y-intercept indicates a distance from the airport, it would suggest how far the helicopter is at the start of its journey.
- If the y-intercept reflects time, it would denote how long the helicopter has been traveling when it starts its journey.

Given the choices, the most fitting interpretation of the y-intercept would be:

C. The helicopter begins its journey 525 miles away from the airport.

This option correctly suggests that at the starting point of the journey (the y-intercept), the helicopter is 525 miles away from the airport.
