Answer
See the graph below:
Work Step by Step
In order to draw the graph of the equation $x+y=4$ , first find any two solutions of the equation.
When $x=0$, the value of y is
$\begin{align}
& 0+y=4 \\
& y=4
\end{align}$
When $y=0$, the value of x is
$\begin{align}
& x+0=4 \\
& x=4
\end{align}$
Thus, two solutions of the equation are $\left( 0,4 \right)\text{ and }\left( 4,0 \right)$.
