# How do you find the slope and intercept of 2x + y = -8?

Dec 29, 2015

Slope $m = - 2$
Y-intercept $= - 8$

#### Explanation:

If the straight line equation is in the form -

$a x + b y + c = 0$

(or)

$a x + b y = c$ Then the formula for its slope is-

$m = - \frac{a}{b}$

In the given problem -

$m = - \frac{2}{1} = - 2$

To find the y-intercept ; put $x = 0$ in the given equation

$2 \left(0\right) + y = - 8$
$y = - 8$
