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

Part A asks for rate of change and initial value - do u know wat they means?
i already did part A. I got: The rate of change is 100 because it went up each year. I know this because i subtracted 350 from 750 and i got 400 and divided it by the number of remaining year.
bx + 350 = 750
Very good :) so 100 is the rate of change...what about the initial value?
