6. Let (R2,(?,?)) be the coordinate plane with the entrywise order. (i) Write explicit inequalities satisfied by x1? and x2? for points (x1?,x2?)?[(?1,?2),(1,3)] (ii) Draw the coordinate graph of [(?1,?2),(1,3)] in the x1??x2? plane (iii) Draw the coordinate graph of the intersection [(?1,?2),(1,3)]?[(?2,1),(2,2)] (iv) Is the intersection [(?1,?2),(1,3)]?[(?2,1),(2,2)] itself a segment? If yes, write it in the form [(a1?,a2?),(b1?,b2?)]
