Multiple Choice:Which of the following situations can be represented by the graph of a linear function?

a) the vertical distance traveled by an elevator over the course of a 24 hr period


b) the position of a hook in the air at the end of a fishing line as it is thrown into the water during the course of several casts


c) the horizontal distance traveled by a golf ball with respect to the time it is driven from a tee


d) the height of a basketball with respect to the time it is thrown toward the basket

Multiple Choice:Which of the following situations can be represented by the graph of a linear function?
A linear function is a constant (straight line) graph.





a) The speed of an elevator is constant, as is it's direction. This can be represented by a linear function.


b) a hook has variable positioning (not constant)


c) a golf ball will move in a parabolic arc (not constant)


d) a basketball will move in a parabolic arc (not constant)





Hence A.
