Unit 5 – System of Equations
![Page 5: Unit 5 introduction systems of equations](https://reader036.fdocuments.net/reader036/viewer/2022081605/58a016b01a28ab9c418b5bdf/html5/thumbnails/5.jpg)
Mrs. Norman’s Tips for Success:1. Attend all Live Learning Classes
2. Take notes while in class
3. Participate during class
4. Ask questions
5. Complete the formative assessments (Practice!!!)
6. Stay after class if you have questions
Failure is NOT an option!

Wrap UpToday we introduced unit 5 and identified solutions to system of equations. We also worked on a level 2 skill for solving a system of equations by graphing. You need to be able to graph a couple of lines on the same graph to find a solution to a system of equations graphically.
