1. Which graph represents a situation for which the rate of change is negative?
A.
B.
C.
D. None of these
graphs represents
a situation for which
the rate of change
is negative.
2. Which statement describes the walk that created the graph shown?
A. The person started 2 m from the motion detector and stood still, then walked
at a constant rate away from the motion detector.
B. The person started 2 m from the motion detector and stood still, then walked at
a constant rate towards the motion detector.
C. The person started 2 m from the motion detector, walked at a constant rate
towards the motion detector, and then stood still.
D. The person started 2 m from the motion detector, walked at a constant rate
away from the motion detector, and then stood still.
3. Beside the graph, write toward or away to indicate what each graph shows.
4. Beside the graph, write moving at a constant speed, speeding up, or slowing down to indicate what each graph
shows.
5. Which option describes a graph that represents a person starting 10 feet from a motion detector and running
towards it at a very fast, constant rate of speed.
A. The graph is a very steep line that starts close to the origin and rises from left to right.
B. The graph is a fairly flat curve that begins high up on the y-axis and falls from left to right.
C. The graph is a horizontal line.
D. The graph is a very steep line that begins high up on the y-axis and falls from left to right.
6. These tables show data from several walks in front of a motion detector. Match each table to a description of the
walk it represents.
7. This graph was created as a student walked in front of a motion detector. The distance was
recorded in meters and the time in seconds. Which statements are true about this walk?
Select all that apply.
A. The student walked toward the motion detector and then walked away from the
motion detector
B. The student walked away from the motion detector and then walked toward the motion detector.
C. The student was not walking at a constant rate
D. The student walked away from the motion detector and then stood still.
E. The student started at 0.55 meters away from the motion detector.
8. Complete this table to show data that will be collected if you start
12 meters away from a motion detector and walk towards the motion
detector at a constant rate of 1.5 meters per second.
9. The graphs show data as Dylan walked in front of the motion detector. During this time period, he was walking at
a rate of ____________ m/sec. (round to the nearest thousandth.)
10. Angelica walked in front of a motion detector. These data represent her walk. Based on the pattern in these data,
which statements appear to be true about the rate at which Angelica walked?
Select all that apply.
A. She walked at
for the first 4 seconds.
B. She walked at
for the first 4 seconds.
C. She walked at the same rate for the entire 8 seconds.
D. She walked at 0
for the last 4 seconds.
E. The data indicate two different but constant rates during Angelica's 8 second walk
