Answer
coincide
Work Step by Step
The solution set for the 2 equations are the same, so are represented by the same line on the graph.
$x\ \ \ \ \ \ \ \ \ 3-x\ \ \ \ \ \ \ \ \ \ y$
$3\ \ \ \ \ \ \ \ \ 3-3\ \ \ \ \ \ \ \ \ \ 0$
$1\ \ \ \ \ \ \ \ \ 3-1\ \ \ \ \ \ \ \ \ \ 2$
$0\ \ \ \ \ \ \ \ \ 3-0\ \ \ \ \ \ \ \ \ \3$
