Cooper is working two summer jobs, making $16 per hour tutoring and making $9 per hour clearing tables. In a given week, he can work no more than 15 total hours and must earn at least $180. Also, he must work no less than 9 hours tutoring and no less than 2 hours clearing tables. If xx represents the number of hours tutoring and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5
