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=4 & & 2x+0=4 \\
y=4 & & 2x=4\\
& & x=2\\
(0,4) & & (2,0)
\end{array}\right] $
Checkpoint (select any x, find the accompanying y):
$\left[\begin{array}{l}
x=3\\
2(3)+y=4\\
y=4-6\\
y=-2\\
(3,-2)
\end{array}\right]$
Plot the points and a line that passes through them
