Writing an Equation from a Story - Kelly Andrews Denney | Library

The video below explains why the y=mx+b equation works for situations in which the pattern (rate of change) is constant. 
Use this pattern to answer the following questions. 

1

Jackie inherited her grandmother's collection of 14 silver bells. Every winter, she gets 2 more. What is the rate of change (aka slope)?
