Breanna, this is the solution to the exercise:
As you can see in the graphs and tables, we have:
1. This is a proportional relationship because we have a graph of a straight line that has a constant slope.
2. This is not a proportional relationship because we have a curved line that does not have a constant slope.
3. This is a proportional relationship because we have a graph of a straight line that has a constant decreasing slope.
4. This is a proportional relationship because y = 2x, and this slope is constant.
5. This is a proportional relationship because y = 7x, and this slope is constant.
6. This is not a proportional relationship because there isn't a constant slope, y is changing for every value of x.
In consequence, the product you need to calculate is:
• 2 * 2 * 2 * 2 * 3 * 3 = 144
