I am struggling with a problem. I need to graph 6x + 3y > 18 on a typical 10 number graph. Can you help me?
I cannot see how to graph 6x+3y>18. I think I shade everything over (0,0) but I can't get to that part because I can't figure the first part out despite looking at the book. I would appreciate...
