How do you graph x+4y=-8?

Jun 20, 2017

see explanation below

Explanation:

$x + 4 y = - 8$

check $x -$intercept when $y = 0$
$x + 4 \left(0\right) = - 8$
$x = - 8$
therefore, $x -$ intercept at $\left(- 8 , 0\right)$

check $y -$intercept, when $x = 0$
$0 + 4 y = - 8$
$4 y = - 8$
$y = - \frac{8}{4} = - 2$
therefore, $y -$ intercept at $\left(0 , - 2\right)$

mark these 2 points of intercept and make a straight line through these 2 points.
