What does it mean when a graph 'stays the same'?

Back

The value does not change over the interval; it is constant.

Front

What is a 'constant rate' of decrease?

Back

A steady decline in value over time, where the amount of decrease is the same in each time period.

Front

What does 'decreasing at a decreasing rate' mean?
