1. Chapter 1: Systems of Linear Equations and Matrices
1.2.1 Gaussian Elimination
SWBAT:
define and use Row-Echelon and Reduced Row-Echelon Form

2. Echelon Form
In the previous set of notes you solved a system of equations and you answer looked like this:
This is an example of a matrix in Reduced Row-Echelon form

3. Which matrices are in Reduced Row-echelon Form?

4. What is another name we could use?
For the Matrices that are not in Reduced row- echelon form, they still look very different than this matrix:
I did this for a reason!
What are the common attributes?
How are they different?
Is there such a thing as column echelon from?
What would it look like?

5. Write the criteria for Reduced row-echelon form:

6. Problems for mastery pg. 19 and 20
1, 2, 3, and write the following as a matrix and write in echelon and reduce echelon form: 6, 8
