15.1 Is this an example of a direct or indirect proportion? Give a reaon for your answer.

To determine whether a relationship is an example of direct or indirect (inverse) proportion, we need to understand the definitions of both: 1. **Direct Proportion**: Two quantities are directly proportional if they increase or decrease together. This means that if one quantity doubles, the other also doubles. Mathematically, this can be expressed as \( y = kx \), where \( k \) is a constant. 2. **Indirect (Inverse) Proportion**: Two quantities are inversely proportional if one quantity increases while the other decreases. This means that if one quantity doubles, the other is halved. Mathematically, this can be expressed as \( y = \frac{k}{x} \), where \( k \) is a constant. To classify the relationship in question (15.1), we need to analyze the context or the specific quantities involved. - If the problem states that as one quantity increases, the other also increases, it is a direct proportion. - If it states that as one quantity increases, the other decreases, it is an indirect proportion. Since the specific details of the quantities in question are not provided, I cannot definitively classify the relationship without additional information. Please provide more context or details about the quantities involved in 15.1 for a precise classification.
