Linear Regression on TI-89

When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a activity that engages scholars to properly label line graphs. It then requests two applied reasoning answers.

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Regressively calculate the bottle usage. Using data about the amount of bottled water and soft drinks consumed an educational video shows pupils how to determine the equation of a linear regression line. After calculating regression...

If your class struggles with graphing inequalities, or if your lecture could use some help from Sal, this video would be a great help. Sal's instruction is measured and patient, and viewers will walk away feeling more confident and...

Using all his tools - tablet, Excel, graphing calculator, and mathematical prowess - Sal orchestrates an algebraic symphony in this video. He works through a word problem involving linear interpolation, and emphasizes the importance of...

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

They say a graph is worth a thousand points. The interactive allows users to graph a wide variety of functions and equations. Using the included keyboard or typing directly into the list, learners determine the graph of a function....

Using the TI-89 calculator, young scholars explore the statistical, graphical and symbolic capabilities of the TI-89.  Students investigate topics such as solving systems of equations, finding inverse functions, summations,...
