This is a PowerPoint lesson that I developed for my Algebra 2 classes to review Chapter 3 of the Prentice Hall CA Algebra 2 textbook. It has 11 problems that review solving system of equations. It could be converted to an Algebra 1 review, but you would need to replace problems that have matrices.
Common Core Standard A-REI
7. Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically.
Previous Standard for Algebra 2 - CA Standard 2.0:
Students solve systems of linear equations and inequalities (in two or three variables) by substitution, with graphs, or with matrices.
I did not create the template. It was offered for free on the Internet.
Note: Math Type 5.0 was used to create many of the slides.
