What to find?
The function that reflects the given ratios given.
Given:
For every eight guests, 2 orders.
To determine the function;
Let y be the number of orders and x be the number of guests.
If for every eight guest, there must be 2 orders, then we will have;

So that, if there are 8 guests, that is; when x=8
