There were 6205 CVS stores in the US in 2006 and 7703 CVS stores in the US in 2013. Write a linear equation in slope-intercept form that models this growth. Let x stand for the number of years after 2006 and let y stand for the number of CVS stores in the US.

Solution

for 2013, x = 7

y = 7703

for 2006, x = 0

y = 6205

so, y- intercept, C = 6205

slope, m = (7703 - 6205) / (7 - 0)

               = 214

So, the linear equation is, y = 214x + 6205 (ans)
