To accurately finish Susie's sentence about linear functions, the following choices should be checked:

- **... be a line.**
- **... have inputs and outputs.**
- **... pass the vertical line test.**

The other choices are not correct because a linear function cannot be a curve, and it can have either a positive or negative slope (or even a slope of zero, which is a horizontal line).
