Question

The graph shows the altitude of a bird over time. A graph measuring altitude and time.

Answer 1

Slope = (5000 -3500)/(2 - 5) = 1500/-3 = -500
slope = -500

answer
The slope is –500 . This means that the bird descends 500 m each minute. 

Answer 2

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 :-

$m=\dfrac{d-b}{c-a}$

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 :

$m=\dfrac{5000-3500}{2-5}\\\\=\dfrac{1500}{-3}=-500$

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
