**Linear Systems**Math 8: Unit 3 Mrs. Tyrpak**Linear System**• A linear system is a set of two equations that contain two variables. • A solution to a linear system is a set of values that work for ALL equations.**Is (-2, 4) a solution to the following systems?**2x + 3y = 8 5x + y = 7 x – 4y = 15 x – 3y = 11**Solving a system graphically**Solve: y = x + 3 y = 2x + 5 Graph the following lines and label their point of intersection.**Solve Graphically**3x + y = 8 4x – 2y = 14 In order to graph we must put in slope intercept form.**Keep up the GREAT work!**Don’t forget to complete your practice and application worksheets. We are beginning to work more algebraically so check your work when possible
