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.
C. The helicopter begins its journey 525 miles away from the airport.
To determine the meaning of the y-intercept of the graph, we need to understand the coordinates at which the graph starts. In this case, the graph starts at the point (0, 525). The first coordinate represents the horizontal axis (time) and the second coordinate represents the vertical axis (distance).
The y-intercept is the point where the graph intersects the y-axis, which is the vertical axis (distance) in this case. Therefore, the y-intercept of the graph is the value of the distance when time is equal to zero.
Based on the information given, option C is the correct answer:
C. The helicopter begins its journey 525 miles away from the airport.
To find this answer, we can analyze the given graph and observe that at the starting point (0, 525), the horizontal axis represents 0 hours and the vertical axis represents a distance of 525 miles. This means that at the beginning of the journey, when time is zero, the helicopter is already 525 miles away from the airport.
