time starting at 2007
t n
0 35250
5 28200
7 ?
n = m t + 35250
28200 = m (5) + 35250
5 m = - 7050
m = -1410
so
n = -1410 t + 35250
if t = 7 years
n = -1410 (7) + 3520
Please i need help with this i don't understand.

To calculate the rate of change, we need to find the difference in population over the given time interval.
Change in population = Population in 2012 - Population in 2007
Change in population = 28,200 - 35,250 = -7,050
Next, we need to determine the number of years between 2007 and 2012, which is 5 years.
Using the rate of change, we can determine the average change in population per year:
Average Change in Population per year = Change in population / Number of years
Average Change in Population per year = -7,050 / 5 = -1,410
Therefore, the approximate population decrease is 1,410 people per year.
To find the approximate population in 2014, we can use the following formula:
Population in 2014 = Population in 2012 + (Average Change in Population per year * Number of years)
Population in 2014 = 28,200 + (-1,410 * 2)
Population in 2014 = 28,200 - 2,820
Population in 2014 = 25,380
Therefore, based on the linear model, the approximate population of the town in 2014 will be about 25,380.
