Identifying Proportional and Non-Proportional Relationships

Why does this graph show a non-proportional relationship?

• It doesn't, it is proportional because it is a straight line

• It goes through the origin

• It does not go through the origin

• It is a straight line

Is the graph proportional or non proportional?

• Proportional

• Non-Proportional

Which graph is non-proportional?

• A

• B

• C

• D

Is the graph proportional or non proportional?

• Proportional because it is a straight line and passes through the origin (0,0).

• Non-Proportional because it doesn't pass through the origin (0,0).
