Question

Which situation can be modeled by a linear function? 
A. The area of a rectangle given its length and width
B. The distance traveled by a person walking at a constant rate
C the velocity of a car on a busy street
D the amount of paint applied to a house

Area will not remain constant as the length and width changes.
Staying the same speed, will give you a constant change. (Correct answer)
A car on a busy street might go from stopping to fast and so on.
Paint applied to a house might change differently for different times.
