# How do you graph 2x+y=-6?

Sep 15, 2017

$\text{see explanation}$

#### Explanation:

$\text{one way is to find the intercepts, that is where the graph}$
$\text{crosses the x and y axes}$

• " let x = 0, in the equation for y-intercept"

• " let y = 0, in the equation for x-intercept"

$x = 0 \to 0 + y = - 6 \Rightarrow y = - 6 \leftarrow \textcolor{red}{\text{ y-intercept}}$

$y = 0 \to 2 x + 0 = - 6 \Rightarrow x = - 3 \leftarrow \textcolor{red}{\text{ y-intercept}}$

$\text{plot "(0.-6),(-3,0)" and draw a straight line}$
$\text{through them}$
