$y = 1, x = 1$ $y=1,x=1$

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

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

So if we set $y = 0$ $y=0$ we get:
$x + 0 = 1 \to x = 1$ $x+0=1 -> x=1$

And similarly, $x = 0$ $x=0$
$0 + y = 1 \to y = 1$ $0+y=1 -> y=1$

Thus we have our intercepts at:

$y = 1, x = 1$ $y=1,x=1$

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