$y (0)$ $y(0)$ and $y (x) = 0$ $y(x)=0$

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

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

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

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

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

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