The y-intercept of a graph represents the value of the dependent variable (in this case, the distance to the airport) when the independent variable (time in hours) is equal to zero.
In this scenario, the y-intercept is 525 miles, which means that at the start of the journey (0 hours), the helicopter is 525 miles away from the airport.
Therefore, the correct answer is:
C. The helicopter begins its journey 525 miles away from the airport.
