Answer
The graph is shown below.
Work Step by Step
The given linear equation is
$\Rightarrow y=0.75x-8$
For the vertical intercept plug $x=0$.
$\Rightarrow y=0.75(0)-8$
Simplify.
$\Rightarrow y=-8$
The vertical intercept is $A=(0,-8)$
Slope is $m=0.75=\frac{3}{4}$, so the rise is $3$ when the run is $4$.
Starting at $(0,-8)$ and going up $3$ and over $4$, we get to $B=(4,-5)$.
Repeat the same to get the next point $C=(8,-2)$.
By using theses three points draw a line.
