A linear equation in "standard form" looks like
$Ax+By=C$

A vertical line is of the form
$x=C$
If $(-5,-2)$ is on the vertical line, then
$x=-5$
or in (expanded) standard form:
$(1)x +(0)y = -5$

Answer 2 · 2015-05-04T13:10:45

$x=-5$ or $x+5=0$
You want a vertical line; so it has always the same $x$ (otherwise it would be inclined) and $y$ can change freely.
The equation $x=-5$ has a fixed value of $x$ (i.e. $-5$ ) and can have any value of $y$ .
