__**Monday/Tuesday Feb. 11/12, 2013 **__

__**Warm-up:**__ __ Objective: __ Thatquiz: Slope of a line: Find m(slope)= Find b(y intercept)= Write equation for the line: y=mx+b Screen shot each slide showing the line Put onto pages open up a text box to complete the slope intercept form.
 * Student will find slope and y-intercept of the line: m=_; b___
 * Student will plug slope and y intercept into the slope intercept form. Giving the Equation of the line: y=mx+b.
 * Algebra
 * Length Open
 * Level 4

SOLVING SYSTEMS OF EQUATIONS BY GRAPHING: Standard: CA 9.0: Solve a system of two linear equations in two variables and interpret answers graphically. Objective 1: Identifying Solutions: Determine whether an ordered pair is a solution of a system of equations. Objective 2: Finding Solutions by Graphing: Find the solution of a system of equations by graphing. Objective 3: Finding Solutions by Substitution: Identify a solution of a system of linear equation by using substitution
 * Continue working on System of Linear Equations Project**

[|System of Linear Equations]


 * Take Notes: Cornell Notes Method
 * Open Grapher and plug in the equations from the following assignments.
 * [[file:mathalvarez2/SystemofGRAPHING1-11.pdf|SYSTEM OF EQUATION BY GRAPHING #1-11]]

1. For each System of Equation student will determine whether the system has 1, infinite or 0 solutions. 2. Student will prove by 1st graphing the set of linear equations. 3. Once student has found the solution by graphing, student will find the solution by proving the solution true by substitution. 4. This will all be shown using the tool of the Macbook Grapher. 5. Each equation will be shown on its own slide. 6. Using color for the different lines and text will make a difference in presentation, so do not leave your graphs black and white.

We will review the assignment and confirm that all students are comfortable with graphing and substitution. Review the video on Elimination and continue with the practice problems [|Elimination Method]
