1. CHAPTER 7-1 SOLVING SYSTEM OF EQUATIONS

2. WARM UP  Graph the following linear functions:  Y = 2x + 2  Y = 1/2x – 3  Y = -x - 1

3. chapter 7-1 notes (solving systems of equations) What value for x would make this statement true? x + 5 = 10 2x + 4 = 16

4.  What values for x and y would make this equation true? X + 3 = y Y = 3x

5.  What values for x and y would make BOTH of these equations true? There can only be one value for x and one value for y. y = x – 1 y = 2x - 3 This is a system of linear equations. That is when you have two or more linear equations together. Our answer to this problem will be the solution of the system of linear equations.

6.  What values for x and y would make BOTH of these equations true? There can only be one value for x and one value for y. y = x + 2 y = 2x - 3

7.  What values for x and y would make BOTH of these equations true? There can only be one value for x and one value for y. y = -.5x + 2 y = -3x - 3

8. y = -2x + 4 y = 3x - 1

9. y = x – 1 y = -x + 7

10.  How to solve a system of equations by graphing: Step 1: Step 2: Step 3:

11.  Practice: Y = 4x + 7y = -x -3y = x Y = -3xy = -2x – 8x = 2y + 2
