you can make a table of values using any intergers and as many as you need in this case I chose 0,1,2 then you replace them in your actual equation and find the values of y.finally plot.
after plotting the points you shade the unwanted region(the sign will direct you) in this case the wanted region is y>.so you shade the less than area.
for the second one you make the equation simpler
6x+3y<9
3y<-6x+9
and also make a table of values,replace were there's x and plot
I hope this helps!

ANSWER
EXPLANATION
The given system of equations is
10x=10
-5x-8y=9
We can rewrite this as:
