Question 1085865: I need an example of how to solve this because I am not solving this correctly. This is my work (which is wrong)because I want it in y=mx+b so that I can get the slope (m) but im only able to solve for x.. please help.
9y+5x>=9y-20
9y+5x=9y-20
+9y
5x=-20
x=-20/5
x=-4, -4,0 but how do I then get the slope so I can graph this?

Question 1086217: A nursery uses two brands of fertilizer for rose bushes.
Brand A costs $3 per pound and provides 280 units of nutrients per pound.
Brand B costs $4 per pound and provides 180 units of nutrients per pound.
-----------------
CONSTRAINTS: The nursery spends $100 or less for fertilizer and wants to provide at least 5200 units of nutrients.
Because brand B contains a special nutrient that brand A does not, the nursery uses at least 4 pounds of brand B.
How many pounds of each should the nursery use to minimize cost?
