Unit Rate Analysis from Graphs

What does the y-axis represent in the graph discussed?

• Time

• Speed

• Miles

• Days

What axis is typically used for the independent variable in a graph?

• y-axis

• x-axis

• z-axis

• None

If a graph point at x=1 shows y=10, what is the unit rate?

• 10 days per mile

• 1 mile per day

• 10 miles per day

• 1 day per mile

How do you determine the unit rate from a graph?

• Divide y by x at any point

• Multiply y by x

• Add y to x

• Subtract y from x

What should you do if there is no point where x equals one on the graph?

• Ignore the graph

• Calculate using another point

• Estimate the closest point

• Restart the graph

In a graph comparing adults to children, what does a point (10, 2) indicate?

• 2 children per adult

• 10 children per adult

• 2 adults per 10 children

• 10 adults per child

What is the unit rate if the graph shows a point at (20, 4) for adults and children?

• 4 adults per 20 children

• 20 adults per child

• 4 children per adult

• 0.2 adults per child

What does a unit rate of '0.2 adults per child' imply?

• For every adult, there are 0.2 children

• For every 2 children, there is 1 adult

• For every child, there are 5 adults

• For every 5 children, there is 1 adult

How can you use a graph's line to predict future amounts?

• By redrawing the graph

• By changing the scale

• By shortening the line

• By extending the line

If you need to predict the number of adults for 60 children, and you know the ratio is 2 adults per 10 children, how many adults would there be?

• 6 adults

• 30 adults

• 12 adults

• 120 adults
