Homework 4.5 (Qualitative Relationships between Two Variables)

The graph shows Pam’s distance from home compared to time. What could segment BC represent?

• Pam slows down to a stop.

• Pam is on her way home.

• Pam is at home.

• Pam is running down a hill away from home.

Which segment shows Pam spending time at home?

• AB

• BC

• CD

• DE

Which scenario could possibly represent the graph below showing Luke’s distance from home compared to time?

• Luke finishes his coffee at the café down the street, begins to ride his bike home when he sees a friend and stops to talk for a few minutes. He walks with his bike the rest of the way home.

• Luke finishes getting ready at home, leaves the house jogging, stops to tie his shoe, then continues walking at a slower pace.

• Luke is running at a constant speed when he begins to slow down. He then continues at a constant slower speed then slows down again until he comes to a complete stop.

• All of the scenarios above could represent this graph.

The graph shows Wally’s speed compared to time. What could segment DE represent?

• Wally is on his way home.

• Wally is walking at a constant speed.

• Wally is walking down a less-steep part of a hill at a constant speed.

• Wally slows down to a stop.

Which segment shows Wally traveling at a constant speed?

• AB

• BC

• CD

• DE

Which scenario could possibly represent the graph below showing Alice’s speed compared to time?

• Alice walks slowly up the first hill, then runs down the other side where she walks to the bottom of the next hill and repeats this pattern.

• Alice leaves home but then realizes she has left her phone at home and goes back to look for it. She leaves home again and then realizes she has also left her purse at home and returns once again for it.

• Alice speeding up and then slowing down to stop at a red light. Then she repeats this pattern at the next red light.

• All of the scenarios above could represent this graph.

Which segment(s) of the graph show air being added to the balloon?

• FG

At which point did the balloon most likely pop?

• Point A

• Point E

• Point F

• Point G

The graph below shows the “Decibel Level” (loudness) of a song being played without adjusting the volume of the speaker.

Which portion of the graph is most likely the “crescendo” (increase in volume to its loudest point) of the song?

• BC

• CD

• DE

• FG

Compare the two graphs below. Which graph shows an extended period of stopping and waiting?

• Graph A

• Graph B

• Both graphs show an extended period of stopping and waiting.

• Neither graph shows an extended period of stopping and waiting.
