  5. CCGPS Coordinate AlgebraDay 21 (10-12-12) UNIT QUESTION: How do I justify and solve the solution to a system of equations or inequalities? Standard: MCC9-12.A.REI.1, 3, 5, 6, and 12 Today’s Question: How do I know where to shade when graphing linear inequalities? Standard: MCC9-12.A.REI.12

  6. Solving Linear Inequalities in two variables Coordinate Plane

  7. Half plane A region containing all points that has one boundary, which is a straight line that continues in both directions infinitely.

  8. Steps for Graphing Inequalities • Get in slope-intercept form • Determine solid or dashed line • Determine whether to shade above or shade below the line (Test Points) • If the test point is true, shade the half plane containing it. • If the test point is false, shade the half plane that does NOT contain the point.

  9. Symbols Shade above > 

  10. Symbols Shade below < 

  11. Symbols Dashed Line < >

  12. Symbols Solid Line  
