To represent the monthly cost \( y \) as a function of the number of additional users \( x \), you can start with the base cost for a single user, which is $9, and then add the cost for each additional user, which is $1 per user.
The equation is:
\[
y = 9 + 1x
\]
or more simply:
\[
y = 9 + x
\]
This shows that the total cost \( y \) is $9 plus $1 for each additional user \( x \).
