GRAPHING SYSTEMS OF EQUATIONS AND INEQUALITIES

I.Systems of Equations A.System – A set of two or more equations. B.Solution – ordered pair that satisfies both equations. C.Coinciding Lines – same slope, same y-int  no unique solution. D.Parallel Lines – same slope, different y-int  no solution. E.Intersecting Lines – different slope  one solution.

F. Examples

II.Systems of Inequalities A.Steps 1.Graph the first inequality and use test point to shade. 2.Graph second inequality and use test point to shade. 3.Overlapping of the shading is the solution set.

B. Examples
