The red graph represents y < -2x + 3
The blue graph represents y > 6x - 9
The solutions of the system of inequalities lie on the red-blue shaded
The part which has two colors
Since the first inequality is y < -2x + 3, the shaded is under the line
Since the second inequality is y > 6x - 9, the shaded is over the line
The common shaded of the two colors represents the area of the solutions of the 2 inequalities
The type of boundary lines is dashed
The points on the boundary lines are
For the red line (0, 3) and (4, 0)
For the blue line (0, -9) and (1, -3)
There is a common point on the two lines (1.5, 0)
