Answer
The graph is shown below.
Work Step by Step
The given linear equation is
$\Rightarrow y=-0.3x+6$
For the vertical intercept plug $x=0$.
$\Rightarrow y=-0.3(0)+6$
Simplify.
$\Rightarrow y=6$
The vertical intercept is $A=(0,6)$
Slope is $m=-0.3=\frac{-3}{10}$, so the rise is $-3$ when the run is $10$.
Starting at $(0,6)$ and going down $3$ and over $10$, we get to $B=(10,3)$.
Repeat the same to get the next point $C=(20,0)$.
By using theses three points draw a line.
