Answer:
The functions have the same initial value
Step-by-step explanation:
As you can see, tour 2 starts at the point (0,35). This is the cost with no people. Tour 1 one the other hand starts at (1,45), not zero. So since the rate of change/slope is 10. Subtract 10 from 45 and you get 35. The same starting point as tour 2.
