The graph below shows the distance between a helicopter and an airport.

The graph titled distance to airport shows distance in miles on the vertical axis and time in hours in horizontal axis. The graph starts at (0, 525) and ends at the point (3.75, 0).

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.

C.

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

The correct answer is C. The y-intercept of the graph indicates the starting point, which is the distance between the helicopter and the airport at the beginning of the journey. In this case, the y-intercept is (0, 525), meaning the helicopter begins its journey 525 miles away from the airport. Therefore, option C correctly describes the meaning of the y-intercept of the graph.

The correct answer is C. The y-intercept of a graph represents the value of the dependent variable (in this case, distance from the airport) when the independent variable (in this case, time) is zero. In other words, at the beginning of the journey when no time has passed, the helicopter is 525 miles away from the airport. Therefore, option C accurately describes the meaning of the y-intercept of the graph.
