Choose the equation of the vertical line passing through the point (8, -2)

Question

anonymous · Answer

Do you know the general form of an equation of a vertical line? If not, it's worth thinking about and trying to deduce it from the properties of a vertical line.

(I suggest people not simply spoil the answer, as it's worth the small amount of thought to figure it out for oneself).

No, I don't know how to.

Well, consider a vertical line (any vertical line - of your choosing!); can you list a few points on this line? Can you say anything about them? If so, can you deduce an equation for a vertical line? Once you've figured this out, you should be apply it to your specific example.

If you can't get it straight away, I suggest you just sit back and think about it for a couple of minutes. Draw a sketch if you feel it would help.
