Which graph represents the solution of this systems of inequalities?

 $x-3y\le-6$  

For questions 3 - 6, use the following scenario:

Bobbi can work at most 20 hours next week, but she needs to earn at least $150. Her dog-walking job pays $6 per hour and her job as a car wash attendant pays $10 per hour. 

Let x = # of hours dog-walking

Let y = # of hours at car wash
