You can put this solution on YOUR website! x+y>1
:
y>-x+1........the boundry line is y=-x+1.
:
it is a dotted line because it is excluded. if the line was included(in other words if there was and equal sign along with the inequality), then it would be a solid line. In order to know what area to shade you need to find points for which the inequality is true.
:
try a couple of points on either side of the line to be sure you havent made a mistake. try (2,2) for instance
:
2>-2+1--->2>-1....this is a true statement
:
now try one on the other side of the line
:
say (0,0)
:
0>-0+1--->0>1......this is NOT true
:
try another one that is on the correct side to be sure. (3,3)
:
3>-3+1--->3>-2....this is true
:
so now you know which side of the boundry line to shade
:
by the way ....I cant make a dotted line here so remember the boundry line is dotted NOT solid
