Finding Unit Rates by Reading Graphs

This lesson teaches how to find unit rates by reading graphs. It begins with an introduction to unit rates using a milk cost example, explaining the concept of constant proportionality. The lesson then explores how graphs provide clues about proportional relationships. A detailed example using a snack pack graph demonstrates how to identify unit rates by analyzing the x and y axes. The lesson concludes with verifying unit rates through multiplication, ensuring that all points on the graph align with the calculated unit rate.

What is the term used to describe the consistent price of milk per gallon across the state?

• Fluctuating rate

• Dynamic rate

• Constant proportionality

• Variable proportionality

When analyzing a graph to find a unit rate, what should you look for?

• The highest point on the graph

• A single quantity on the x-axis

• The intersection of the axes

• The slope of the line

If one snack pack contains 120 calories, how many calories would three snack packs contain?

• 600 calories

• 480 calories

• 360 calories

• 240 calories

How can you verify the unit rate on a graph?

• By checking if the graph is a straight line

• By multiplying other quantities by the unit rate and matching the y-axis points

• By finding the midpoint of the graph

• By comparing it to another graph

What is the unit rate of calories per snack pack if the graph shows 120 calories for one snack pack?

• 200 calories per snack pack

• 150 calories per snack pack

• 100 calories per snack pack

• 120 calories per snack pack
