Finding a linear equation and graphing it.
Not what you're looking for?
Suppose that the amount that your town's population grows each year is fixed (or constant). Choose the amount of population growth each year.
(Hint: Choose a whole number for your growth rate, rather than a percent.)
A) Year(t) Population (P)
t=0
(2010)
t=1
(2011)
t=2
(2012)
t=3
(2013)
t=6
(2016)
B) Find a linear equation in the form P=mt+b(y=mx+b), which gives the population, P, t years form 2010.
C) Use your equation in part b to approximate the population in the year 2030.
D) Use your equation in part b to approximate how many years it will take the population to reach 7000.
E) Graph this function in Ms Excel by plotting the x-axis and population on the y-axis.
