### High School Mathematics - 27.6 Solutions of System of Linear Inequations in Two Variables

 Example: Solve the following linear inequalities graphically. x+y >= 5 x-y <= 3 Solution: The graph of the equation x+y = 5 is shown in the graph below. The solution of the inequality x+y <= 5 is the shaded region above the line x+y = 5 including the points on the line. On the same set of axes we draw the graph of the equation x-y = 3. The solution of the inequality x-y <= 3 is the shaded region above the line x-y = 3 including the points of the line. Directions: Draw the graph of the following inequalities.
