Graph single or multiple inequalities of the form x < a, x ≤ b, x > c, x ≥ d on a number line.
This interactive calculator helps you graph single or multiple linear inequalities on a number line. It supports all standard inequality operators: <, ≤, >, and ≥, and provides instant visual feedback with shaded regions and boundary points.
Easily enter one or more inequalities at once.
The calculator automatically plots all inequalities on the same number line.
The calculator draws a number line showing:
This makes it simple to see where the inequalities hold true.
As you type your inequalities:
You can instantly verify and understand the solution set.
The graph updates in real time as you type. Perfect for students, homework, and exam preparation — no manual plotting needed.
1️⃣ Select the number of inequalities you want to graph (1–5), then enter each inequality with its operator and value.
2️⃣ The calculator plots a horizontal number line as the coordinate axis.
3️⃣ For each inequality:
4️⃣ When multiple inequalities are entered, all solution sets are displayed together on the same number line for easy comparison.
5️⃣ Use the "Clear All" button to reset inputs, or "Reload Calculator" to reset everything and start fresh.
Suppose you enter:
x ≥ 2 and x < 5
The calculator displays:
A number line with a closed circle at 2, an open circle at 5, and the region between 2 and 5 shaded.
This represents all real numbers x such that 2 ≤ x < 5.
Everything you need to know about graphing linear inequalities on a number line quickly and accurately.
This calculator allows you to graph **one or multiple linear inequalities** on a 1D number line. For each inequality, it automatically:
