# How do you find the x and y intercepts for x + y = -9?

Nov 20, 2015

$y \left(0\right)$ and $y \left(x\right) = 0$

#### Explanation:

$y \left(0\right)$ gives you the interception with the y-axis, since $x = 0$

$0 + y = - 9$
$y = - 9$
That gives us $\left(0 , - 9\right)$

$y \left(x\right) = 0$ gives us the interception with the x-axis because$y = 0$.

$x + 0 = - 9$
$x = - 9$

This gives us interception with x-axis at$\left(- 9 , 0\right)$
