Description

Rapidly build understanding of linear relationships with Slope Slider's beautiful, novel interface!

Color-coded dynamic numbers and unparalleled user-friendliness make linear relationships second nature.

This app is much more than a graphing calculator, the way a face-to-face conversation is more than a text message. Users of this app are immersed in a world of lines. As the user changes values in their equations, the lines move to instantly reflect those changes.


Since many lines may be graphed independently, the user can compare one line to another, to see and understand how changing this 2 or that -1 will be reflected graphically, and a "trace" feature allows the user to see the whole family of lines generated by changing a parameter.

All of the power of Apple's innovative user interface is put to work in this app, with the goal of increasing real understanding of linear relationships.

Bells and whistles include:

• Take pictures of graphs, which can then be texted or emailed anywhere
• Save your favorite graphs for re-use later
• Display a table of values to show the linear relationships numerically
• Show values either in decimal or fraction form
• Input decimal values directly, or let Slope Slider convert them from fractions
• In-depth help and readily available pop-up tips make sure you never get lost

What's New in Version 1.2

Slope Slider now graphs inequalities! Some improvements have been made to drawing speed as well.

Worst. App. Ever.

Do not download. They should pay you to buy this app. I cannot believe apple allows the company to put this horrible app on the app store. Very confusing. With just one wrong button you screw up the whole app. My math teacher made me download this app. A waste of space on your apple product. If you download this you will be crying on the floor from its horribleness. This app will make you throw your phone at the wall then throw it in the trash. Do. Not. Buy.

Good app

I like how the slope and y-intersect are color-coded so you can easily see that when the intercept changes that the graph moves up or down and if the slope changes so does the steepness of the line. It will be great to use this as a demo in my classroom.

Meh

Helps me in geometry but when it comes to me having to subtract on it or have a number bigger than 10 then it crashes
