You can put this solution on YOUR website!
Identify ordered pair data points. You want number of campers as the dependant variable, and time, or year
as the independant variable.

(2005, 450); five years later, ROSE TO 750 campers, so the point is (2010, 750).
You want a linear equation representing this relationship. Take your choice on how.

m=%28750-450%29%2F%282010-2005%29=300%2F5=60.
Using the first ordered pair with point-slope form equation,
y-450=60%28x-2005%29
y=60%28x-2005%29%2B450
y=60x-60%2A2005%2B450
highlight%28y=60x-119850%29

Another way to handle this is to call year 2005 as time ZERO, and then your x would be number of
years since year 2005. You would get a different y-intercept value.
