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\\
0-4y=8 & & x-0=8 \\
-4y=8 & & x=8\\
y=-2 & & \\
(0,-2) & & (8,0)
\end{array}\right] $
Checkpoint (select any x, find the accompanying y):
$\left[\begin{array}{l}
x=4\\
(4)-4y=8 \\
-4y=8\\
y=-2\\
(4,-2)
\end{array}\right]$
Plot the points and a line that passes through them
