The graph shows the distance, y, in miles, of an eagle from its nest over a certain amount of time, x, in minutes. Graph titled Distance Vs Time is shown with Time in minutes along the x-axis and Distance from Nest in miles along the y-axis. The scale on the x-axis shows the numbers 0 to 40 at increments of 8, and the scale on the y-axis shows the numbers 4 to 32 at increments of 4. A straight line joins the ordered pairs 0, 16 and 8, 20 and 16, 24 and 24, 28 and 32, 32.

Based on the graph, what is the initial value of the graph and what does it represent?

16 miles per minute; it represents the speed of the eagle
0.5 mile per minute; it represents the speed of the eagle
0.5 mile; it represents the original distance of the eagle from its nest
16 miles; it represents the original distance of the eagle from its nest
