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
