To express the relationship between the number of cups remaining \( y \) and the number of days the pet feeder has been used \( x \), we start with the initial amount of food, which is 8 cups. Since the feeder dispenses 1 cup of food each day, the amount of food remaining decreases by 1 cup for each day that passes.
We can write the equation as follows:
\[
y = 8 - x
\]
In this equation:
- \( y \) represents the number of cups remaining,
- \( x \) represents the number of days the pet feeder has been used.
As days go by (as \( x \) increases), the value of \( y \) (cups remaining) decreases.
