Answer:
The graph in the attached figure
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
The slope of the dashed line is negative
The y-intercept of the dashed line is 3
The x-intercept of the dashed line is 9
----> inequality B
The solution of the inequality B is the shaded area above the dashed line 
The slope of the dashed line is positive
The y-intercept of the dashed line is 2
The x-intercept of the dashed line is -2/3
The solution of the system of inequalities is the shaded area between the two dashed lines
see the attached figure
