Graphing Relationships and Ratios

The video tutorial covers lesson 7.1, focusing on guided practice with ratios. It begins with instructions for students to attempt problems independently before checking answers. The tutorial explains the constant ratio of oxygen to sulfur atoms in sulfur dioxide, demonstrates how to simplify and complete a table of these ratios, and guides students in graphing the relationship. It then moves to a similar exercise with stickers, maintaining a width-to-length ratio, and concludes with a problem involving the ratio of candles to boxes. Each section emphasizes understanding and graphing equivalent ratios.

What should you do before resuming the video according to the instructions?

• Watch the video again.

• Check your answers with a friend.

• Try the problems on your own.

• Read the textbook.

What is the simplified ratio of oxygen to sulfur atoms in sulfur dioxide?

• 3:1

• 2:1

• 1:2

• 1:1

How do you find the missing term in the table for sulfur dioxide?

• By subtracting the numbers.

• By multiplying by a constant factor.

• By adding the numbers.

• By dividing by a constant factor.

What is the relationship between the rows in the sulfur dioxide table?

• The rows are equal.

• The bottom row is twice the top row.

• The top row is three times the bottom row.

• The top row is half the bottom row.

What is the equivalent ratio of 12 over 6 in the sulfur dioxide table?
