Explain why or why not the table below represents a proportional relationship.
Screenshot Of The Table..
1. This is not a proportional relationship because the x values "go up" by different amounts each time.
2. This is a proportional relationship because the rate of change (slope) between all the points is 5.
3. This is not a proportional relationship. The rate of change is a consistent 5, but it does not start at (0,0).
4. This is a proportional relationship because the proportion of the values is consistent with the increase over the course of the table.
