Life Savings--Andrea is plotting how much money she has in her bank account over time. She starts with $30 and every week she saves $5 more.

Is the following statement true or false?

"Using only the graph, Student McStudentson can tell that this is a proportional relationship because it is a straight line."

BE CREATIVE--Create your own table and graph that shows a relationship that is NOT proportional.

Make sure to...

1) Write out a word problem

2) Complete the table

3) Complete the graph and explain why it is not proportional.
