The graph below shows the distance, y, in miles, of a bird from its nest for 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 25 at increments of 5, and the scale on the y axis shows the numbers 1 to 8 at increments of 1. a straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7. based on the graph, what is the initial value of the graph and what does it represent?
