2. Solve Linear Systems by Graphing Objective: Graph and solve systems of linear equations.

3. A linear system consists of two or more linear equations in the same variables. Example: x + 2y = 7 and 3x – 2y = 5 A solution to a linear system in two variables is an ordered pair that satisfies each equation in the system. A system that has exactly one solution is called a consistent independent system. All systems in the first four sections of Chapter 7 will be consistent independent systems; other types will come up in section 5.

4. What is the solution to this system of equations? Name two ways to tell whether (2, 0) would be a solution to this system. (3, 1)

5. Solve the linear system by graphing: 2x + 5y = 7 -x + 2y = -8 Put into slope-intercept form or make a table. Graph both lines. Find the intersection point. Check the solution algebraically.

6. Solve the linear system by graphing: -x + y = 5 2x + y = 8 Put into slope-intercept form or make a table. Graph both lines. Find the intersection point. Check the solution algebraically.

7. SVHS is selling football tickets for a home game. The school sold 35 tickets for $86 on the first day of the sale. Student tickets cost $2 each and non-student tickets cost $3 each. Find the number of student tickets and the number of non-student tickets the gym sold. Name your variables. Write your equations. Solve the system by graphing.
