#### Answer

$\text{a) Slope-Intercept Form: not possible}
\\\\\text{b) Standard Form: }
x=2$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$
To find the equation of the line with the following properties:
\begin{array}{l}\require{cancel}
\text{Vertical }
\\\text{Through: }
(2,5)
,\end{array}
use $x=a.$
$\bf{\text{Solution Details:}}$
Vertical lines take the form $x=a.$ Since the line passes through $(2,5),$ then the equation of the line is
\begin{array}{l}\require{cancel}
x=2
.\end{array}
The equation of the line is
\begin{array}{l}\require{cancel}
\text{a) Slope-Intercept Form: not possible}
\\\\\text{b) Standard Form: }
x=2
.\end{array}
