SUMMARY

Graphing inequalities such as x > 7 is achievable in Geometer's Sketchpad (GSP). Users can create visual representations of inequalities on both number lines and in the plane. Key resources include sketches provided by Shawn Godin and others, available at isenegger.ca. Additionally, a collection of resources for GSP can be found at mathfest.blogspot.com, which includes professional discussions on similar topics.

PREREQUISITES
  • Familiarity with Geometer's Sketchpad (GSP) software
  • Understanding of basic algebraic inequalities
  • Knowledge of graphing techniques on number lines
  • Ability to navigate online resources and forums for educational support
NEXT STEPS
  • Explore the sketches at isenegger.ca for practical examples of graphing inequalities
  • Review the collection of resources for Geometer's Sketchpad at mathfest.blogspot.com
  • Learn about advanced graphing techniques in GSP
  • Participate in the Math Forum discussion group for further assistance and insights
USEFUL FOR

Mathematics educators, students learning algebra, and anyone interested in visualizing inequalities using Geometer's Sketchpad.

Does anyone know how to graph x > 7 with Geometer's Sketchpad? Is it possible?

Inequations in Sketchpad

It is possible to graph inequalities on a number line or in the plane.

Shawn Godin supplied the first sketch (see isenegger.ca/GSP/greater_less.gsp) and I am not sure where I picked up the other (isenegger.ca/GSP/inequality3.gsp).

I have been collecting resources for Sketchpad - see mathfest.blogspot.com/2008/05/resources-for-geometers-sketchpad.html, including the mathforum discussion group where questions like this are routinely and professionally answered. If you need any help deconstructing the methods used in either sketch above, you can contact me through my blog.

Hope this helps,

Ross
