Answer
Refer to the graph below.
Work Step by Step
Find the x-intercept by setting $y=0$ then solving for $x$:
$2x-4y=-8
\\2x-4(0)=-8
\\2x=-8
\\\frac{2x}{2}=\frac{-8}{2}
\\x=-4$
Thus, the x-intercept is $(-4, 0)$.
Find the y-intercept by setting $x=0$ then solving for $y$:
$2x-4y=-8
\\2(0)-4y=-8
\\-4y=-8
\\\frac{-4y}{-4}=\frac{-8}{-4}
\\y=2$
Thus, the y-intercept is $(0, 2)$.
Plot the intercepts, then connect them using a line.
