Question

Select Linear or Nonlinear to correctly classify each function.
Function Linear Nonlinear
y=−10.2


y=3x2+7


3x + 5y = 15


y=2x−9

Answer 1

Here’s the classification of each function:

1. **y = -10.2**: Linear
2. **y = 3x² + 7**: Nonlinear
3. **3x + 5y = 15**: Linear
4. **y = 2x - 9**: Linear

### Summary:
- Linear: y = -10.2, 3x + 5y = 15, y = 2x - 9
- Nonlinear: y = 3x² + 7
