# Graphing inequalities on a number line

What software or websites for graphing inequalities on a real number line?

• Try Desmos. – Lucian Nov 26 '14 at 18:10
• @Lucian: Desmos can do a number line with some trickery, but it is not easy. The site I linked to says "Desmos doesn’t do linear inequalities in one variable" and "it would still be pretty cool if Desmos would add one-variable number line graphing functionality." Geogebra is much easier. – Rory Daulton Nov 26 '14 at 19:22

You might want to check out geogebra, with which you can graph inequalities on a number line and oh so much more than that. That is, it enables you to do many graphing tasks, simple and complicated.

You can download the software (free of charge), and I believe you can work with geogebra online.

• I often use Geogebra but did not know it could be easily used for a number line. (I didn't realize you can easily hide the $y$-axis.) $+1$ for the tip! Here is a YouTube video discussing how to make a number line in Geogebra. – Rory Daulton Nov 26 '14 at 16:45
