What does the y intercept mean?
The rate of change is___ after the first 6 weeks because as the weeks increase the money decreases.
The given scenario is nonlinear because the rate of change is different before and after week 6.
The y-intercept in this scenario is $50. It is the initial amount of money Ryan had before any weeks passed.
The y-intercept represents the starting point of the line or graph, which in this case is the amount of money Ryan had at the beginning.
The rate of change after the first 6 weeks is negative or -10. This means that for every week after week 6, Ryan's money decreases by $10.
