The y-intercept represents the starting point of the situation, in this case, the number of cookies. The slope represents the rate of change of cookies over time.
For example, if the y-intercept is 20 cookies, it means that at the beginning of the situation there are 20 cookies.
If the slope is 5 cookies every day, it means that the number of cookies increases by 5 every day.
So, in this situation, the simplest rate using whole numbers for the slope would be 5 cookies per day.
