Assumptions
- Inputs for `y-intercept-calculator` follow the on-page labels; values/shapes must match this operation.
- Units (when shown) must be consistent across inputs for y-intercept.
- Real-number arithmetic is used unless y-intercept explicitly needs integers.
Limitations
- Y-Intercept Calculator cannot invent missing inputs; incomplete forms stop short of a forged y-intercept value.
- Display rounding can differ slightly from a CAS/symbolic exact form of y-intercept.
- Complex/branch cuts and undefined points are not always interactively annotated for y-intercept.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
