Graph Proportional Relationships (Lesson 5)

From your work on Table 1 and Graph 1, choose the best description.

• The graph is proportional, because the constant rate of change is 15.

• The graph is proportional, because it is linear and intersects the origin.

• The graph is non-linear, because there is no constant rate of change.

• The graph is non-proportional, because it does not intersect the origin.

From Table 2 and your graph, choose the best description.

• The graph is proportional, because it has a constant rate of change of 7

• The graph is proportional, because it is linear and crosses the origin.

• The graph is non-proportional, because it is not linear.

• The graph is non-proportional, because it does not cross the origin.

The constant rate of change (constant of proportionality) for graph 5 is ________.

The constant rate of change (constant of proportionality) for graph 6 is ________

In 3 months, JoAnne saved $150. After 6 months, there is $300 in the account. I would expect there to be ___ dollars in her account after 12 months.
