Understanding Ratio Tables and Graphs

The lesson focuses on using ratio tables to represent information, converting them into ordered pairs, and graphing these pairs to visualize relationships. The example of Dominic mowing lawns is used to illustrate how to set up a ratio table, create ordered pairs, and graph them. The graph is extended to answer questions about future scenarios without additional calculations. The concept of slope and its representation in the graph's equation is also discussed.

What is the main focus of this lesson?

• Studying geometric shapes

• Representing information in a ratio table and graphing it

• Learning about algebraic equations

• Understanding fractions

What does Dominic charge for mowing one lawn?

• $15

• $10

• $12

• $20

How can you organize information to create an ordered pair?

• By using a pie chart

• By using a ratio table

• By using a bar graph

• By using a histogram

What is the relationship between the x and y axes in this context?

• X-axis represents time, Y-axis represents speed

• X-axis represents lawns, Y-axis represents charge

• X-axis represents charge, Y-axis represents lawns

• X-axis represents distance, Y-axis represents time

What is the first ordered pair in the ratio table?

• (1, 12)

• (2, 24)

• (3, 36)

• (4, 48)

What should a graph in a ratio table always form?

• A dotted line

• A zigzag line

• A curved line

• A straight line

• 15

• 20

• 25

• 30

What is the slope of the graph in this context?

• Money equals 10 times lawns

• Money equals 15 times lawns

• Money equals 12 times lawns

• Money equals 20 times lawns
