Question

How do you find the x and y intercepts for `x + y = 1`?

Answer 1

`y=1,x=1`

Explanation:

Here is a graph of the equation:
graph{1-x [-10, 10, -5, 5]}

We can see the y-intercept is given where `x=0` and the x-intercept is given where `y=0`,

So if we set `y=0` we get:
`x+0=1 -> x=1`

And similarly, `x=0`
`0+y=1 -> y=1`

Thus we have our intercepts at:

`y=1,x=1`
