Here is the study guide along with the answer key for our upcoming test on systems of equations.

In this lesson, we focused our attention on word problems that necessitated us using systems of equations to solve.
In this lesson, we learned another way to solve systems of equations called elimination. We had a brief discussion about when it would be better to use elimination and when it's best to use substitution.
On Monday, we solved systems of equations using substitution, and discussed the conditions that would lend themselves to using this method over another.
We finished out the week by discussing conditions where systems of equations had either one solution, no solutions, or infinitely many solutions. We then did a few examples before students were released to complete exercises in groups using Desmos.
We introduced the first of three ways we would be solving systems of equations--by graphing them. We identified a solution to a system of equations as the point where two lines crossed on a coordinate plane. This definition would be refined in later lessons...
the first lesson of the new year introduced students to concept of systems of equations. We looked at what it meant to be a system, and what it meant for something to be a solution to a system.
Here you go. Study guide for the next test on Dec 15. Answer key below.
This final lesson of 2016 looked at comparing proportional relationships by looking at the slope of a graph.
This is lesson 19--we looked at finding equations for lines when it might be more challenging than simply looking at a graph. What if the y-intercept is NOT on the graph? What to do then?
