Proportional vs Non-Proportional

Proportional vs Non-Proportional

Learning Target

• I can determine if a graph is proportional or not.

Proportional vs Non-Proportional

• I graph is known to be proportional if it passes through the origin.

• It increases at a steady (constant, proportional) rate.

Proportional vs Non-Proportional

• Does the line pass through the origin?

• Because the graph does not pass through the origin....it is not proportional.

Proportional vs Non-Proportional

• Does the line start at (0,0)?

• Since the line starts at the origin, this graph is proportional.
