Question

If I have the points (-1,-8) ; How do I write the equation of the vertical line passing through it ?

Answer 1

vertical line :-
x = k

Answer 2

since the point has a x-coordinate of -1,
the equation wud be ?

Answer 3

I know what a vertical line is -_- I need to know how to write the EQUATION for the GIVEN POINTS .

Answer 4

Yes :)
just we look at the x-coordinate of give point

Answer 5

-1 .

Answer 6

since the point has a x-coordinate of -1,
the equation wud be \(x = -1\)

Answer 7

So that's it . My answer for this question : Write the equation of the horizontal line passing through the point (-`,-8) is x= -1 ?

Answer 8

yup !

Answer 9

So if I had this same question , but with different points & it asked for a vertical line , it would by y= ?

Answer 10

if i had (3,1) it would be y=1 ?

Answer 11

vertical line is always like below :-
x = somthing

Answer 12

vertical line passing thru (3, 1) wud be x = 3

Answer 13

but x is for horizontal lines .. ?:I

Answer 14

thats a very good question :)

Answer 15

i think it has to be in slope intercept form .. y=mx+b or something .

Answer 16

tell me this,
wats the equation of y-axis ?

Answer 17

I dunno .
I'm not in school & I dont have anyone teaching this stuff to me .

Answer 18

im probably making you angry . :c

Answer 19

its okay, since now im here, lets discuss this and get some clarity on vertical/horizontal lines :)

Answer 20

its easy to see that, on y axis all points have x = 0

Answer 21

mhm ..
