Answer 1

In summary, a "constant rate of change" is when something changes consistently and does not change much in pattern.

It's best to break down each answer choice and ask if the changes noted in each one are consistent or not.

For choice A, the number of people of a city bus can change so much, especially depending on the time of day, holidays, and work days.

For choice B, the price of grapes in general can change a lot depending on the market, and you oftentimes won't have a consistent weight either.

For choice C, a girls feet will grow as the girl gets older. That is something that will be relatively constant on a graph.

For choice D, the time it takes to deliver a pizza will always vary, depending on traffic, cooking time, and how busy the store is. There is nothing constant about that!
