The solution for x+1/2y=1 in ordered pair form is (1, 0) because that is where the line passes the x-axis. It also crosses the y-axis at point (0, 2). If these are not possible answer choices to your problem, then anything plotted on the line I have graphed in the attachment should work as the answer. ;)
I also provided attachments to help show which points on the graphed line are what ordered pairs. One of those should totally work for your answer! :D
