Is this a proportional equation?  Why?

• It is not proportional because it doesn't have a constant.

• It is not proportional because it doesn't have a constant rate of change.

• It is proportional because if x = 0, y = 0.

• It is proportional because it has a y intercept.

The graph shows the water level as a bathtub fills.  Select the correct choice that describes this graph.

• The graph is proportional because the y to x ratio is constant (the same).

• The graph is non-proportional because it does not pass through the origin (0,0).

• The graph is proportional because it is linear (a straight line).

• The graph is non-proportional because it is linear (a straight line).
