Question

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

Answer 1

`y(0)` and `y(x)=0`

Explanation:

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

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

`y (x) = 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`(-9 , 0)`
