Answer: [tex]x=2[/tex]

Step-by-step explanation:

Given

Line passes through [tex](2,-5)[/tex]

and parallel to y-axis

If a line is parallel to another line then they must possess same slope

slope of y-axis is [tex]\tan 90^{\circ}[/tex]

Now Equation of line is given by

[tex]\Rightarrow \dfrac{y-(-5)}{x-2}=\tan 90^{\circ}[/tex]

we know [tex]\tan 90 \rightarrow \infty [/tex]

[tex]x-2[/tex] must be zero for [tex]\dfrac{y-(-5)}{x-2}\rightarrow \infty[/tex]

So, [tex]x=2[/tex] is the equation of required line
