I believe the answer is y = -3x + 15
This is what I got from calculating it but I haven’t done this type of equation in a while
The y values are not changing so y = 6 describes the line
When you take this problem and simplify it you get 9p-3
1 hour = 60 minutes
60 minutes / 10 minutes = 6
So 6 times in one hour 3 buses depart.
6 x 3 = 18 total buses in an hour.
