Plase! a plane is on its approach to land on the runway. the jet’s height above the ground is given in feet as a function of the time in seconds. the following table tracks the plane as it lands:
t (in seconds) h (in feet)
0 4000
5 3500
10 3000
15 2500
20 2000
25 1500
is this function linear? if it is, what is the slope? use the formula m= △h/△t

The function is linear

Slope is -100

Step-by-step explanation:

Given :

t (in seconds)      h (in feet)

0                            4000

5                            3500

10                           3000

15                           2500

20                           2000

25                           1500

Solution:

To check whether the function is linear or not we will use two point slope form:

Now substitute the values

Now check the given points ,whether they satisfies the obtained equation:

(10,3000)

Hence satisfied

Thus the function is linear :

Now to find slope:  

So,  

Hence the slope is -100

it is part of the rising action that reveals public sentiment toward hester.
