We are given
The first time a census was taken in Michele Corners, the population was 1772
so, initial population =1772
so, 
Each year after that, the population was about 9% higher than it was the previous year
so, r=9%

now, we can use formula

y is population after x years
x represent the number of years since the first census was taken
so, we get equation as


y-intercept:
so, we can plug x=0 to get y-intercept
