### Solving Systems with Matrices and All Things Linear

 From Pearson Education Algebra II will be putting algebra basics behind them and moving on to linear equations with a coordinate geometry twist and an introduction to the concept function.  The goal of this week is to recall all you have learned about linear equations and really push your understanding of linearity to the limit.  Please find the Pearson PowerPoint slides below, a collection of videos on lines, the homework, and a linear equations reference sheet!

These videos are aligned to the sections from your textbook, so as you are completing homework from your textbook you can easily locate the most relevant videos for you!
_______________________________________________________________________________ Precalculus will continue to develop the properties of matrices and apply them to solving systems of equations. We will complete the final investigation of this unit on mixtures and solidify our ability to organize and manipulate information using matrices and apply them in problem-solving contexts.
