7.5 Graphing Linear Inequalities

Pre Test for Unit #6 Test over Chapter 7

There will be a test over Unit #6 which covers material from Chapter 7 in our text. The test will be on FRIDAY DECEMBER 14.  The main topic covered is solving systems of equations with one section on linear inequalities. A great way to review would be to complete the Chapter 7 Pre Test which can be found at this link:

Here is another teaching video for 7.1  

7.1 Solving a System of Equations by Graphing

To solve a system of equation by graphing:
-Graph both equation on the same coordinate plane.
             -  If the equations are not in y=mx+b form then they need to be put in that form
-The point where they intersect is the solution.
-Remember you have the option of checking your answers by substituting (x,y) back in.
