For the line x-2y>0
To know the shading part, put any point which is not lies on the line, say (4, 0) for this line.
On putting (4, 0) we get 4-0>0 =>   4 > 0 This is true.
So we shade the portion in which (4, 0) lies.
Suppose if we get a false we shade the portion in which the point does not lie.

In order to ensure optimal health (and thus accurate test results), a lab technician needs to the dogs a daily diet containing a minimum of 24 grams (g) of fat, 36 g of carbohydrates, and 4 g of protein. But the dog should be fed no more than five kg of food a day. Rather than to order dog-food that is custom-blended, it is cheaper to order Food X and Food Y, and blend them for an optimal mix. Food X contains 8 g of fat, 12 g of carbohydrates, and 2 g of protein per kg, and costs Rs0.20 per kg. Food Y contains 12 g of fat, 12 g of carbohydrates, and 1 g of protein per kg, at a cost of Rs0.30 per kg. What is the optimal blend?
