Question 1009718: Show all work as you solve the linear modeling problem below.
There were 5475 CVS stores in the US in 2005 and 7250 CVS stores in the US in 2010. Write a linear equation in slope-intercept form that models this growth. Let x stand for the number of years after 2005 and let y = the number of CVS stores in the US.

You can put this solution on YOUR website!
let x=year
y=stores
2005/5475
2010/7250
slope is 1775/5=355
use point slope formula
y-y1=355(x-x1)
y-5475=355(x-2005)
y-5475=355x-711775
y=355x-706300.
If 2005=0 and 2010=5,
y-5475=355x
y=355x+5475
