1. 2.8B Graphing Absolute Value Inequalities in the Coordinate Plane 1. Find location of the absolute value “V”  a I x – h I + k 2. Determine if graph is solid or dashed.  SOLID: ≤ or ≥  DASHED: 3. Determine if the area shaded is above or below the graph.  ABOVE: > or ≥  BELOW: < or ≤

2. Determine if a point is a solution Is (x, y) a solution? Put x and y values into original inequality. If result is a TRUE statement, then it is a solution. Graph inequality. Is the point in the shaded area? If yes, it is a solution.

3. Examples: Graph each Y > -2 I x – 3 I + 4 Y ≥ - I x + 3 I – 2 Y < 3 I x – 1 I – 3
