Answer
Refer to the graph below.
Work Step by Step
Solve for $x$.
$-3x-24=0
\\-3x-24+3x=0+3x
\\-24=3x
\\\frac{-24}{3}=\frac{3x}{3}
\\-8=x$
This means the given equation is equivalent to, and has the same graph as $x=-8$.
RECALL:
The graph of an equation of the form $x=h$ is a vertical line whose x-intercept is $(h, 0)$. Each point on the line has an x-coordinate of $h$.
Thus, the graph of $x=-8$ is a vertical line whose x-intercept is $(-8, 0)$. Each point on the line has an x-coordinate of $-8$.
This means that the following points are all on the line:
$(-8, -2)$, $(-8, 0)$, and $(-8, 2)$
Plot the three points listed above then connect them using a line to complete the graph.
