# How do you graph 2x+4y=-8 using intercepts?

Mar 19, 2017

$x$ intercept = $- 4$

$y$ intercept = $- 2$

#### Explanation:

$2 x + 4 y = - 8$

Divide by $- 8$

$\frac{x}{-} 4 + \frac{y}{-} 2 = 1$

$x$ intercept = $- 4$

$y$ intercept = $- 2$

Graph of the above equation is as follows:

I would first solve the equation for y.

#### Explanation:

$2 x + 4 y = - 8$

$4 y = - 8 - 2 x$

$y = - 2 - \left(\frac{1}{2}\right) x$

Now simply choose a few values for x and solve for y. The intercepts will be both the coordinates determined by the x and y value.
