Answer: The slope is –500 . This means that the bird descends 500 m each minute
Step-by-step explanation:
The slope of a line that passes through (a,b) and (c,d) is given by :-
[tex]m=\dfrac{d-b}{c-a}[/tex]
From the graph , the x-axis is representing time in minutes and y-axis is representing altitude in meters .
The line is passing through (2,5000) and (5,3500).
Then, the slope of the line will be :
[tex]m=\dfrac{5000-3500}{2-5}\\\\=\dfrac{1500}{-3}=-500[/tex]
I.e. slope =- 500.
Since , the slop is negative it means the bird descends 500 m each minute.
Hence, the correct answer is
The slope is –500 . This means that the bird descends 500 m each minute
