Slide 1: Opening Assignment  How do you graph a linear equation and inequality?
Slide 2: Smith Project Reflection    What did you do well as a team? What would you do differently? What was difficult/confusing about the project?
Slide 3: Systems Assessment   Systems test is on Wednesday Assessment will cover:      Definition Types of Solutions Recognizing a Solution Solving systems Modeling a system
Slide 4: Systems Assessment Review  Definition  A system of equations/inequalities is two or more equations or inequalities  Example: Ax + By = C Dx + Ey = F  Example: Ax + By > C Dx + Ey < F
Slide 5: Systems Assessment Review  Solution of two linear equations    None (parallel) One (intersecting) Infinite (same line) Looking at a graph Placing the solution into the original equations  Recognizing a solution to a system  
Slide 6: Systems Assessment Review  Methods to solve a system    Graphing Substituting Elimination Creating equations from a given situation like the smith project  Modeling a system 
Slide 7: State the solution to the graph
Slide 8: State the solution to the graph
Slide 9: State the solution to the graph
Slide 10: State a solution to the graph
Slide 11: In-Class Practice Problems  Students graph the following problems and state the solution:  y = 1/2x - 5 y = 1/2x + 3  y = -5 - x x + 3y = -15  x-y>3 y < 15
Slide 12: Home Practice Problems  Students graph the following problems and state the solution:  y = -2x - 7 y = 2x + 8  x > -7 y < 10 x<y
Slide 13: What is the solution to the graphed system of equation? A. B. C. D. (2,2) (-2,2) (-2,-2) (2,-2)
