Refer to the Explanation.

$x + y = 1$ $x+y=1$

First solve for $y$ $y$ . This will put the equation into slope-intercept form.

$y = - x + 1$ $y=-x+1$

Table of Values
$x = 2,$ $x=2,$ $y = - 1$ $y=-1$
$x = 1,$ $x=1,$ $y = 0$ $y=0$
$x = 0,$ $x=0,$ $y = 1$ $y=1$

Plot the points and draw a straight line through the points.

graph{y=-x+1 [-9.14, 10.86, -3.03, 6.97]}
