Answer
(a) $x=3$.
(b) $x-3=0$
(c) Refer to the attached image for the graph.
Work Step by Step
(a)
RECALL:
The equation of a vertical line is $x=a$ where $a$ is the x-intercept. All the points in this line has an x-coordinate of $a$.
Thus, the equation of a vertical that passes through the point $(3, -2)$ is $\color{blue}x\color{blue}=\color{blue}3$.
(b) The general equation of a line is $Ax + By + C = 0$, where A, B are not both zero.
Thus, the general form of the vertical line's equation is:
$x-3=0$
(c) To graph the line, plot the points (3, 2), (3, 0), and (3, -2) then connect them using a line. (Refer to the attached image in the answer part for the graph)
