I’d like to check that a studnet input is a linear inequality of any type. That’s it, nothing else.

Seems fairly simple, but I’m growing to believe this may be a shortcoming of Desmos’ methods.

This works for equations but not for inequalities:

```
check=isDefined(xyLine(this.latex))
```

Fair enough I suppose. However parsing Inequalities by left and right doesn’t seem to allow for stictching it back together in such a way as to determine properties such as angle, etc. that would allow for linearity checking, even though it can very happily be graphed.

Any thoughts on this? Thanks!
