# 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

• 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
