Proportional vs Non-Proportional Graphs in Snowboarding

The video tutorial covers the concepts of proportional and non-proportional graphs. It explains how to identify proportional relationships by checking if a graph is a straight line and passes through the origin. The lesson includes examples and exercises to help students understand these concepts. The tutorial concludes with a summary and homework instructions.

What is the main difference between the red and blue lines in the first set of graphs shown?

• The red line is curved, and the blue line is straight.

• The red line is proportional, and the blue line is not proportional.

• The red line is above the blue line.

• The red line is longer than the blue line.

In Example C, what are the input and output values?

• Input is the number of calories, and output is the number of minutes.

• Input is the number of minutes, and output is the number of calories.

• Input is the x-value, and output is the y-value.

• Input is the y-value, and output is the x-value.

In Example B, what is the conclusion about the relationship based on the graph?

• It is not proportional because it does not pass through the origin.

• It is proportional because it is a curved line and passes through the origin.

• It is not proportional because it is not a straight line.

• It is proportional because it is a straight line and passes through the origin.
