IXL - Identify graphs: word problems (Algebra 1 practice)

Camila's quinceañera is coming soon! As the RSVPs arrive, she tracks the number of people who have responded and whether or not they will be able to attend. In the beginning, the RSVPs arrive at a slow but steady rate. Then, she receives a lot of last-minute responses.

Which graph could show the number of RSVPs Camila receives leading up to her quinceañera?

question

Caden's science class is studying tadpoles. Each tadpole is born with a tail, which it keeps for a few weeks. Once the tadpole starts to become a froglet, its tail shrinks away to nothing.

Which graph could show the length of the tadpole's tail in relation to its age?

solution

You want to find the graph that could show the length of the tadpole's tail in relation to its age. So, consider each part of the story and what the graph should show.

Caden's science class is studying tadpoles. Each tadpole is born with a tail, which it keeps for a few weeks.

Since each tadpole already has a tail when it is born, the graph will not start at a length of 0 millimeters. For a few weeks, the length of the tail does not change. The graph should show a horizontal segment that starts at more than 0

millimeters.

Once the tadpole starts to become a froglet, its tail shrinks away to nothing.

After a few weeks, the tail shrinks, so its length decreases until the tail is gone. The graph should show a decreasing

segment.

This graph shows all of the parts of the story in order:
