Answer:
P(t) = 27000 - 4*t
Step-by-step explanation:
Over a period of time, if we know the population at certain time, and the rate of change of the population, we can express the function describing such population by means of these two parameters
Then:
P(t) = P₀ + 4*t
In our case
P(t) = 27000 - 4*t
Sign minus is for decreasing population t is in months, 4 is the rate of change and finally 27000 was population the first time Talulah counted the population

Step-by-step explanation:
Answer:
or 
Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to

we have the ordered pairs
(3,-5) and (1,-9)
substitute the values



step 2
Find the equation in point slope form

Analyze two cases
<em>First case</em>
we have


substitute

<em>Second case</em>
we have


substitute

Note: The equation of the line in point slope form varies according to the point you choose, in contrast to the slope-intercept form
