Question

As part of an Earth Science project, Erin tracked the amount of rain fall for 4 weeks. She started tracking after finding some initial data on the year's rainfall to date:

Answer 1

If the linear function representing the amount of rainfall each week is f(w) = 2.5w + 3, what does the 3 represent in this function?
The amount of rainfall in week 0
The week that Erin collected data
The amount of total rainfall
The amount the rainfall increased each week

Answer 2

Answer 3

f(x) = mx + b where b is the y-intercept. So 3 is the y-intercept, which is the amount of rainfall in 0 weeks
