Answer
The graph is shown below.
Work Step by Step
The given linear equation is
$\Rightarrow f(x)=-\frac{2}{3}x$
The equation is in the form of $f(x)=mx+b$
Where, $m$ is the slope and $b$ is the $y-$ intercept.
From the equation slope is $-\frac{2}{3}$.
and $y-$ intercept is $0$.
Now plot the point $(0,0)$.
For the second point use rise over run,
$\Rightarrow m = -\frac{2}{3}= \frac{-2}{3}=\frac{Rise}{Run}$
By using slope the next point is $2$ units down and $3$ units to the right.
Hence, the second point is $(3,-2)$
Draw a straight line through the two points.
