Hi there! Thank you for the opportunity to help you with your question!

The slope of this line is given by (number of CVS in 2011 - number of CVS in 2007)/(2011 - 2007) = (7389-6301)/4 = 272. So the slope is 272.

Now, the y intercept is given by the number of stores in 2007, or 6301.

The line equation is y = 272x +6301 (note that if you plug in x = 4, you recover the number 4 years after 2007, or 2011)


Please let me know if you need any clarification. Always glad to help!
