Answer
See the graph below:
Work Step by Step
In order to draw the graph of the function $f\left( x \right)=-\frac{1}{3}x+2$, replace $f\left( x \right)$ with y.
$y=-\frac{1}{3}x+2$.
So, put $x=0$ in the equation and get
$\begin{align}
& y=-\frac{1}{3}\left( 0 \right)+2 \\
& y=2
\end{align}$
Again, put $x=3$ in the equation and get
$\begin{align}
& y=-\frac{1}{3}\left( 3 \right)+2 \\
& y=-1+2 \\
& y=1
\end{align}$
Thus, two solutions of the equation are $\left( 0,2 \right)\text{ and}\left( 3,1 \right)$.
