Which graph represents a linear function increasing at a constant rate?
It is nonlinear because it increases at a constant rate.
Mary and Kim each take 15 minutes to ride their bikes to school. The graphs of the functions that model their rides are shown, where x is the time, in minutes, and y is the distance, in miles.
The graphs are divided into time intervals A, B, C. Use the graphs to match each statement with the appropriate person or people.
Mary rode her bike fastest in Interval A, as compared to the rest of her ride.
Kim rode her bike fastest in Interval A, as compared to the rest of her ride.
Mary stopped for an interval of time.
Kim stopped for an interval of time.
Mary rode slower in Interval C than in Interval B.
