i didnt understand how the shaded region

Which region

Incomplete question

I think you are asking for shading in chapter 6.....nd if yes it is as first of all we plot the points on graph by taking x and y zero one by one nd then we check whether the condition is true or false by putting both the x and y zero simultaneously. If the condition is true then we shade towards the origin nd if false we shade away from the origin. For furher help see the pic.

I think you are asking for chaptr 6 if yes then here is your answer
At first to find out the shaded region we have to find the points on the graph .
After finding the graph plot the points on the graph and make a stright line joining them .
Now , if it is greater than 0 then it should be shaded away from the origin and if it is less than 0 then it should be near to the origin .
Here is a simple example of it ??

Hope it will be helpful
