Answer
$$x + y = 4$$
points on the graph
$(0,4), (4,0)$
Work Step by Step
$$ x + y = 4$$
We can graph the equation by finding the x-intercept and the y-intercept.
if $x=0$
$$ x + y = 4$$ $$ 0 + y = 4$$ $$ y = 4$$
Thus, we have point $(0,4)$.
if $y=0$
$$ x + y = 4$$ $$ x + 0 = 4$$ $$ x = 4$$
Thus, we have point $(4,0)$.
