Proportional or not?
If you are looking at a table or graph, there has to be a constant for it to form a proportional relationship. You have to get the same number every time when you take y and divide it by x. If you don't get the same number, then it is not proportional.
We can also look at a graph and tell if it forms a proportional relationship. The graph of a proportional relationship has to form a straight line and it also has to go through the origin, which is the point (0,0) on a graph. The picture above shows a line that forms a proportional relationship.
