Graphing and Analyzing Rates

The video tutorial explains how to graph ratio relationships using various examples. It begins with a simple example of flour and water, showing how to plot points and draw a line to represent the ratio. The tutorial then moves to a time and earnings example, followed by calculating the cost of dark chocolate cashews per pound using a graph. Finally, it compares the rising rates of a hot air balloon and a blimp, demonstrating how to use graphs to determine which rises faster.

What is the first step in graphing a ratio relationship?

• Draw a line on the graph

• Calculate the slope

• Find the midpoint

• Create a ratio table

In the flour and water example, what is the ratio of flour to water?

• 3:1

• 2:1

• 4:1

• 1:1

How much do you earn in 3 hours according to the time and earnings graph?

• $20

• $10

• $30

• $40

What is the cost of 2 pounds of dark chocolate cashews?

• $37.50

• $25.00

• $50.00

• $12.50

How can you determine the cost of 2.5 pounds of cashews using the graph?

• By using a calculator

• By asking a friend

• By looking at the graph

• By guessing

What is the height increase of the hot air balloon every 3 seconds?

• 12 meters

• 5 meters

• 9 meters

• 7 meters

Which rises faster, the hot air balloon or the blimp?

• The hot air balloon

• The blimp

• It cannot be determined

• They rise at the same rate

What is the height increase of the blimp every 2 seconds?

• 6 meters

• 8 meters

• 7 meters

• 5 meters

How do you graph the points for the blimp's rise?

• Use a bar graph

• Draw a circle

• Estimate the points

• Plot points and draw a line

What is the purpose of connecting the dots on a graph?

• To visualize the relationship

• To confuse the viewer

• To make it look nice

• To add more data
