SOLUTION: The number of Starbucks stores in the US in 2005 was 8896. In 2014, there were 11,965 Starbucks stores in the US. Let y be the number of Starbucks stores in the US in the year x

Question 1128054: The number of Starbucks stores in the US in 2005 was 8896. In 2014, there were 11,965 Starbucks stores in the US. Let y be the number of Starbucks stores in the US in the year x, where x = 0 represents the year 2005.

a) Write a linear equation in slope-intercept form that models the growth in the number of Starbucks stores in the US in terms of x. [Hint: the line must pass through the points (0, 8896) and (9, 11965)].

b) Use this equation to predict the number of Starbucks stores in the US in the year 2020.

c) Explain what the slope for this line means in the context of the problem.

slope is change in y over change in x or 3069/9=341
Point slope formula y-y1=m(x-x1, m is slope and (x1, y1) point
y-8896=341x
y=341x+8896
in 2020, x will be 15
y=341*15+8896=14,011
slope is the number of new Starbucks formed every year.
