**Hank's Relationship:** - **Graph Behavior:** Does not pass through the origin. **Lynn's Relationship:** - **Graph Behavior:** Passes through the origin. **Proportionality:** - **Only Lynn's relationship is proportional.**

Solución

To determine whether the relationships between the number of months and the total amount paid are proportional for Hank and Lynn, let's analyze their payment structures: 1. **Hank's Payments:** - **Up-front Payment:** \$2,000 - **Monthly Payment:** \$200 The total amount Hank pays can be expressed as: \[ \text{Total Paid} = \$2,000 + \$200 \times (\text{Number of Months}) \] This equation represents a linear relationship but **not a proportional relationship** because there is an initial payment (\$2,000) that doesn't depend on the number of months. A proportional relationship requires that when the number of months is zero, the total amount paid is also zero. 2. **Lynn's Payments:** - **Up-front Payment:** \$0 - **Monthly Payment:** \$275 The total amount Lynn pays can be expressed as: \[ \text{Total Paid} = \$275 \times (\text{Number of Months}) \] This equation represents a **proportional relationship** because there is no initial payment. When the number of months is zero, the total amount paid is also zero, satisfying the condition for proportionality. **Dropdown Selections:** 1. **A graph that shows the number of months and the total amount paid by Hank would:** - **Not Pass Through the Origin** 2. **A graph that shows the number of months and the total amount paid by Lynn would:** - **Pass Through the Origin** 3. **The relationship between the number of months and the total amount paid is proportional for:** - **Lynn only**

When we look at Hank's payments, his graph will not pass through the origin since he made a down payment of $2,000, which means it's not a proportional relationship. The total amount paid by Hank is modeled by the equation \( y = 200x + 2000 \). In contrast, Lynn's payments start at zero because she had no upfront cost, making her relationship proportional. Her total payments can be modeled by \( y = 275x \), and the graph will pass through the origin. Therefore, the relationship between the number of months and the total amount paid is proportional for Lynn but not for Hank.
