How do you graph an inequality like x ≥ 2 on a number line?

Place a closed (filled) dot at 2 because 2 is included, then draw a ray extending to the right with an arrowhead pointing toward positive infinity to show every number greater than 2. If it were x > 2, you would use an open (hollow) dot instead. In this tool, add an Interval, set the left endpoint to 2 as closed, and check +∞ for the right side.

What is the difference between an open and a closed dot?

A closed (filled) dot means the value is included — used for ≤, ≥, or a plotted point that belongs to the set. An open (hollow) dot means the value is the boundary but is excluded — used for .

How do I put fractions on a number line?

Set the tick step to the fraction denominator (for example 1/4 for fourths) so the ticks land exactly on the fractions, then enable fraction labels. The tool positions each tick precisely and labels them as n/d rather than decimals.

Can I make a number line with negative numbers?

Yes. Set the minimum to a negative value (such as -10) and the maximum positive. Zero sits wherever it falls in the range, with negative numbers to its left and positive numbers to its right.

Can I download or print the number line?

Yes. The Precise number line mode exports a clean SVG or a high-resolution PNG (rendered at 2x) that you can drop into worksheets, slides, and homework. Precise mode runs entirely in your browser and does not use image-generation credits.

When should I use the AI sketch mode instead?

Use AI sketch mode for illustrated or themed number lines — colorful counting lines for young learners, temperature or timeline scales, or word-problem scenes. For exact tick spacing, precise fractions, and correct inequality endpoints, use the Precise number line mode.

What is a number line?

A number line is a straight horizontal line on which every point corresponds to a real number. A chosen point marks zero, numbers increase to the right and decrease to the left, and evenly spaced tick marks show the scale. Because the spacing is uniform, a number line lets you compare sizes, add and subtract by moving along it, and locate fractions, decimals, and negative numbers visually.

How to plot points on a number line

Pick a range and a tick interval (the step) so the values you need land on or between ticks. Major ticks are labeled with their number; minor ticks subdivide each interval for finer values.
To plot a value, place a dot at its position. A filled (closed) dot marks a value that is included; a hollow (open) dot is used for a boundary that is excluded, which matters when graphing inequalities.
In the Precise number line mode you add points, type their values, toggle closed or open, and pick a color — the tool positions each dot exactly by mapping the value to its coordinate.

Graphing inequalities and intervals

Inequalities are shown as a shaded segment or ray along the line. Use a closed (filled) endpoint for ≤ or ≥ and an open (hollow) endpoint for < or >.
For x ≥ 2, put a closed dot at 2 and draw a ray extending right with an arrowhead toward +∞. For x < 5, put an open dot at 5 and shade left. A bounded interval such as 1 ≤ x < 4 uses a closed dot at 1, an open dot at 4, and a bar between them.
In the tool, add an Interval, set its endpoints (or check −∞ / +∞ to make that side a ray), and toggle each end closed or open. The renderer draws the correct dot style and adds an arrowhead when a side runs to infinity.

Fractions and decimals on a number line

To place fractions, choose a step equal to the fraction denominator — for fourths, set the step to 1/4 so ticks fall on 0, 1/4, 1/2, 3/4, 1. Turn on fraction labels and the tool writes ticks as n/d instead of decimals. Decimals work the same way: a step of 0.1 or 0.5 spaces the ticks evenly, and any point value (like 2.5) is positioned precisely between ticks.

Tips for clean, printable number lines

Choose a step that keeps labels readable — too many major ticks crowd the numbers, so use minor ticks for the in-between marks instead.
Keep the range tight around the values you care about so the diagram fills the width without wasted space.
Use color sparingly to distinguish separate points or intervals, and export as SVG for infinitely crisp printing or PNG (rendered at 2x) for slides and documents.
