Answer
Graph:
Work Step by Step
Intercepts (set x=0, find the y; set y=0, find the x:
$\left[\begin{array}{lll}
x=0, & & y=0\\
0+y=2 & & x+0=2 \\
y=2 & & x=2\\
& & \\
(0,2) & & (2,0)
\end{array}\right] $
Checkpoint (select any x, find the accompanying y):
$\left[\begin{array}{l}
x=3\\
3+y=2\\
y=-1\\
\\
(3,-1)
\end{array}\right]$
Plot the points and a line that passes through them
