IM 7.2.12 Lesson: Using Graphs to Compare Relationships
Find the product mentally.
Diego, Lin, and Mai went from the ticket booth to the bumper cars. Use each description to complete the table representing that person’s journey.
Diego left the ticket booth at the same time as Tyler. Diego jogged ahead at a steady pace and reached the bumper cars in 30 seconds.
Lin left the ticket booth at the same time as Tyler. She ran at a steady pace and arrived at the bumper cars in 20 seconds.
Mai left the booth 10 seconds later than Tyler. Her steady jog enabled her to catch up with Tyler just as he arrived at the bumper cars.
Draw a graph of all four people’s journeys (including Tyler's from the other day).
Which person is moving the most quickly? How is that reflected in the graph?
Write equations to represent each person’s relationship between time and distance.
Meteoroid Perseid 245 and Asteroid x travel through the solar system. Explore the applet to learn about the distance they had each traveled after a given time.
Is Asteroid x traveling faster or slower than Perseid 245? Explain how you know.
The graph shows the price of different lengths of two types of rope.
If you buy $1.00 of each kind of rope, which one will be longer? Explain how you know.
