I mostly need help writing a linear inequality, I think I might be able to graph it though.

You have two part-time jobs. One is ar a grocery store, which pays $9 per hour, and the other is mowing lawns which pays $6 per hour. Between the two jobs, you want to earn at least $150 per week. Write a linear inequality that shows the different numbers of hours you can work at each job, and sketch the graph of the inequality. From the graph, find several ordered pairs with positive integer coordinates that are solutions of the inequality.
