Sarah has been running a dog-walking business since 2010. She walks dogs twice a day, takes them to the park, and returns them to their homes. Each year, she has increased her fee by the same amount. The table shows what Sarah charged each customer for two given years of her business: Year Annual Dog-walking Fee 2010 $350 2014 $750 A. What is the rate of change and initial value for Sarah’s business? How do you know? B. Write an equation in slope-intercept form to represent the fees that Sarah charges each year.

    Correct. What is the initial value, i.e. the rate she charged when she started the business in 2010?

    would the equation be y=100x+4? @ospreytriple

    No. The rate of change part is correct (100x). But, instead of +4, it must be the initial value (the rate charged when the business first opened). What would it be?
