Inequality graphing on a TI-84 style workflow is less about decoration and more about seeing where expressions are above, below, or equal to each other. Once you understand the logic, the screen becomes a very practical visual checker.
Rewrite the inequality into a graph-friendly form
If the problem is already in y form, the process is simpler. If not, move terms so you can compare one side against the other more clearly.
Use boundary thinking before shading thinking
The related equality often tells you where the important border lives. Once you understand the boundary, deciding which side is valid becomes much easier.
Test points when the region is not obvious
If the graph or algebra feels ambiguous, pick a simple test x-value or point and check whether it satisfies the inequality. That reduces the chance of trusting the wrong side of the visual pattern.
Key takeaways
- Find the boundary first, then decide which side is valid.
- Test points are often the fastest way to confirm a shaded region.
- The equality version of the problem usually does much of the setup work.
