Ratio Tables and Proportions

The video tutorial explains how to graph ratio relationships on a coordinate plane. It begins with an introduction to graphing ratios, followed by a practical example of graphing hours worked and earnings. The tutorial then covers the use of ratio tables to understand and graph relationships, and concludes with graphing ratios from a recipe. Throughout, the importance of maintaining equal spacing on axes and correctly plotting ordered pairs is emphasized.

What is typically placed on the x-axis when graphing time-related data?

• Earnings

• Time

• Distance

• Temperature

In the context of the video, what does the y-coordinate represent when plotting hours worked?

• The number of tasks completed

• The amount of time spent

• The number of hours

• The amount of earnings

If a person earns $54 in 6 hours, how much do they earn per hour?

• $7

• $9

• $6

• $8

What is the first ordered pair for the recipe ratio table?

• (9, 15)

• (6, 10)

• (3, 5)

• (5, 3)

How are the numbers on the x-axis spaced in the recipe ratio table?

• By twos

• By threes

• By fours

• By fives

What is the relationship between eggs and cups of flour in the recipe ratio table?

• 2 eggs to 3 cups

• 4 eggs to 6 cups

• 3 eggs to 5 cups

• 1 egg to 2 cups

If you have 9 eggs, how many cups of flour are needed according to the ratio table?

• 10 cups

• 12 cups

• 15 cups

• 18 cups

What would be the next ordered pair if the ratio table continued beyond 9 eggs?

• (15, 25)

• (12, 20)

• (18, 30)

• (12, 18)

How many cups of flour are needed for 7 eggs based on the extended ratio?

• 17 cups

• 10 cups

• 12 cups

• 14 cups

If you have 10 eggs, approximately how many cups of flour would you need?

• 15 cups

• 17 cups

• 20 cups

• 22 cups
