x<=6 the first thing i do is make this x=6 this is a vertical line which you plot by drawing a line from the six up..this should be easy...

next one is y>=1..y=1 wouldnt this be a horizontal line on the plan which you plot from 1?

the next one is 2x-y>=-1 first thing i do is solve for x by making 4 zero so 2x =-1/x=-1/2 so the set is (-1/2,0)

then i solve for -y =-1 which when i am done with all the negatives is y=1 which gives the set (0,1)

the book graphs these points as (6,1) (0,1) and (6,13) what the heck?
