Show all work as you solve the linear modeling problems below.

There were 338 Krispy Kreme Doughnuts stores in the US in 2003 and 222 Krispy Kreme Doughnuts stores in the US in 2008. Write a linear equation in slope-intercept form that models this decline. Let x stand for the number of years after 2003 and let y stand for the number of Krispy Kreme Doughnuts stores in the US.

Solution

338 Krispy Kreme Doughnuts stores in the US in 2003 and 222 Krispy Kreme Doughnuts stores in the US in 2008

x stand for the number of years after 2003 and let y stand for the number of Krispy

So, we have points : ( 0, 338) and ( 5 , 222)

slope = (222- 338)/(5 -0) = -116/5

y = mx + c ; c = 338 ; y = -116x/5 + 338

So, y = -116x/5 + 338
