The x-axis shows the passage of time.
Number of birds is representd on the y-axis.
From the graph, we observe that,
when time = 1 minute, number of birds = 8
When time = 2 minutes, number of birds = 6
Therefore, the relation between the number of birds and time is
n = 10 - 2t
Therefore, number of birds after 3 minutes = 10 - 2(3) = 4
