To determine whether each equation is linear or nonlinear and whether it is a function or not, we can analyze each one step by step.

1. **Equation: (y + 7) = 3(x - 2)**
- **Linear/Nonlinear**: This is a linear equation because it can be rewritten in the form \(y = mx + b\). Rearranging gives us \(y = 3x - 6 - 7\) or \(y = 3x - 13\).
- **Function/Not a Function**: This is a function because for each x-value there is exactly one y-value.

2. **Equation: 25 = x² + y²**
- **Linear/Nonlinear**: This is a nonlinear equation because it describes a circle (implicit form), which is not a straight line.
- **Function/Not a Function**: This is not a function because for some x-values, there are two corresponding y-values (one positive and one negative).

Here’s how you can summarize this information:

| Equation | Linear | Nonlinear | Function | Not a Function |
|---------------------------------|----------------|----------------|--------------------|---------------------|
| (y + 7) = 3(x - 2) | Yes | | Yes | |
| 25 = x² + y² | | Yes | | Yes |
