Example: Solve the following linear inequalities graphically. x+y >= 5 xy <= 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 xy = 3. The solution of the inequality xy <= 3 is the shaded region above the line xy = 3 including the points of the line.
Directions: Draw the graph of the following inequalities.
