1. Name:__________ warm-up Chapter 3 review SALES The Daily Grind charges $1.25 per pound of meat or any fraction thereof. Draw a graph that represents this situation. Identify the function shown by the graph.

2. Graph y = |x| + 1. Identify the domain and range. Notebook question: What was your grade on your Chapter One End of Chapter test?

3. Details of the Day EQ: Why do we need to use two equations to solve a problem? I will be able to… Solve system of equations by graphing, elimination and substitution Activities: Warm-up Review Chapter Two Notes: Systems of Equations Class work/ HW Vocabulary: System of Equations Elimination Substitution.

4. Chapter 3: Solving System of Equations Review

5. A Quick Review SALES The Daily Grind charges $1.25 per pound of meat or any fraction thereof. Draw a graph that represents this situation. Identify the function shown by the graph.

6. A Quick Review Graph y = |x| + 1. Identify the domain and range.

7. Notes and examples

8. Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it. x + y = 3 y = –x Use the graph to determine whether the system is consistent or inconsistent and if it is independent or dependent. 2y + 3x = 6 y = x – 1

9. Notes and examples Use substitution to solve the system of equations. y = –4x + 12 2x + y = 2

10. Notes and examples Use elimination to solve the system of equations. –3x + 4y = 12 3x – 6y = 18
