  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.
