Answer:
Create a function representing number of published articles per month:
[tex]a=12m+60[/tex]
Where:
- a = total number of articles published
- m = number of months
- 12 = slope = number of articles published per month
- 60 = y-intercept = number of published articles at the start (month 0)
Now substitute in the values of m to get the a-value:
- m = 1 → a = 12(1) + 60 = 72
- m = 3 → a = 12(3) + 60 = 36 + 60 = 96
- m = 4 → a = 12(4) + 60 = 48 + 60 = 108
- m = 9 → a = 12(9) + 60 = 108 + 60 = 168
