Question 1047739
<font face="Times New Roman" size="+2">


A vertical line is a set of ordered pairs such that the *[tex \Large x] coordinates are all equal.  In order for a vertical line to go through the point *[tex \Large (a,b)], all of the *[tex \Large x] coordinates must be equal to *[tex \Large a], so the equation would be *[tex \Large x\ =\ a].  All you need to do now is apply this principle to your particular situation -- in other words, replace *[tex \Large a] with the abscissa of your given point.
