Determines the solution region for linear inequalities on a number line or coordinate plane.
For ax + b < c:
- Draw line x = (c - b)/a
- Shade region where inequality is true
- Use solid line for ≤ or ≥, dashed line for < or >
Graph shows solution region where inequality is satisfied

Worked Examples
Example 1: Number Line
Graph x < 3 on number line
- inequality: x < 3
- graphType: number-line
- boundary: x = 3 (open circle)
- solutionRegion: All points to the left of 3
- graphDescription: Open circle at 3, arrow pointing left
Example 2: Board Level
Graph 2x + 1 ≤ 5 on number line
- inequality: 2x + 1 ≤ 5
- graphType: number-line
- boundary: x = 2 (closed circle)
- solutionRegion: All points to the left of and including 2
- graphDescription: Closed circle at 2, arrow pointing left
About this calculator
Overview
Inequality Graph Calculator evaluates Inequality Graph for the math / linear-inequalities library. Primary input cue: Inequality [required]: Inequality expression (e.g., '2x + 3 < 7', 'x - 5 ≥ 2'). Method anchor: For ax + b < c: - Draw line x = (c - b)/a - Shade region where inequality is true - Use solid line for ≤ or ≥, dashed line for < or >. Graph shows solution regi.
When to use
Use Inequality Graph Calculator when you already know the inputs and need inequality graph without setting up a spreadsheet.
Inputs explained
- Inequality [required]: Inequality expression (e.g., '2x + 3 < 7', 'x - 5 ≥ 2')
- Graph Type [optional]: Type: 'number-line' or 'coordinate-plane'
Formula / method
For ax + b < c: - Draw line x = (c - b)/a - Shade region where inequality is true - Use solid line for ≤ or ≥, dashed line for < or >. Graph shows solution region where inequality is satisfied (calculator id: inequality-graph-calculator).
Worked example
Worked values: inequality = x < 3, graphType = number-line → boundary = x = 3 (open circle), solutionRegion = All points to the left of 3, graphDescription = Open circle at 3, arrow pointing left
Interpreting results

Assumptions
- Units (when shown) must be consistent across inputs for inequality graph. [inequality-graph-calculator]
- Empty required inputs are not silently replaced with zeros for inequality graph.
- Real-number arithmetic is used unless inequality graph explicitly needs integers.
Limitations
- This page does not provide a full textbook proof for every identity related to inequality graph.
- Inequality Graph Calculator cannot invent missing inputs; incomplete forms stop short of a forged inequality graph value.
- Complex/branch cuts and undefined points are not always interactively annotated for inequality graph.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
