Question

Neil started a stamp collection with 12 stamps. Every week , he adds 4 more stamps to the collection. Which function? F represents the relationship between the number of stamps (s) and the number of weeks (w)

Answer 1

`s=4w+12`

Explanation:

Let

s -----> the number of stamps

w ----> the number of weeks

we know that

The linear equation that represent this situation is

`s=4w+12` ----> equation of the line into slope intercept form

where

the slope m is equal to
`m=4\ stamps/week`

the y-intercept b is equal to
`b=12\ stamps` ---> (the initial value)
