Question

Complete Horizontal and Vertical Lines Problems

1. Give the coordinates of two points on the line x = 5.

2.Give the coordinates of two points on the line y = -2.

3.Write the equation of the horizontal line passing through the point (-1, -8).

4.Write the equation of the vertical line passing through the point (3, 1).

5.Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?

6.Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

Answer 1

we need to remember below two forms :-

vertical line : x = k
horizontal line : y = k

Answer 2

look at first question,
we're given line x=5, is it vertical or horizontal ?

Answer 3

we make up a random problem

Answer 4

wat ? dint get u...

Answer 5

nothing lol i dont underdstand the problem

Answer 6

lol ok :)

1. Give the coordinates of two points on the line x = 5.

it is asking us to give two points on that line

Answer 7

can u tell me, if x = 5 is horizontal or vertical ?

Answer 8

vertical

Answer 9

yes :)
so it x value is fixed at 5

Answer 10

all the points on that line will be like this :-
(5, k)

Answer 11

you can pick any value for k

Answer 12

since they want 2 points, lets pick two random points :-

(5, 1) and (5, 2)

Answer 13

they both will lie on line x = 5

Answer 14

this is the first question?

Answer 15

yes

Answer 16

based on how we did first question, can u try 2nd question ?

Answer 17

no lol this is hard

Answer 18

its ok :)

Answer 19

2.Give the coordinates of two points on the line y = -2.

Answer 20

its a horizontal line, so points on it will be of form :-
(k, -2)

Answer 21

u can pick any value for k, just pick two random values

Answer 22

u pick

Answer 23

ok, my lucky numbers today are 8 and 2 :)

(8, -2) and (2, -2)

Answer 24

those two points will lie on y = -2 line

Answer 25

Next,
3.Write the equation of the horizontal line passing through the point (-1, -8).

Answer 26

read the question, what is it they want ?

Answer 27

the want an equation

Answer 28

Yes, they want an equation of horizontal line passing thru (-1, 8)
now look at my first reply, and tell me this :-
wats the form of horizontal line ?

Answer 29

y=k

Answer 30

Yes !

since the y coordinate of given point is 8, here

the equation of line wud be :

y = 8

Answer 31

okay

Answer 32

4.Write the equation of the vertical line passing through the point (3, 1).

Answer 33

can u try this ?

Answer 34

i dont know :(

Answer 35

its fine :) look at my first reply, and can u tell me equation for form of vertical line ?

Answer 36

x=k

Answer 37

it has to pass thru (3, 1)
so, the vertical like wud be,

x = 3

Answer 38

5.Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?

Answer 39

im sure you can answer this q now, try... :)

Answer 40

virtical

Answer 41

Yes !

Answer 42

x=4 is vertical, and tje slope of vertical line is UNDEFINED

Answer 43

ok

Answer 44

wat about the last question ? :)

Answer 45

horizontal

Answer 46

awesome !! y = -6 is a horizontal line, and slope of horizontal line is ZERO

Answer 47

*y=-8

Answer 48

is this it we finishes?

Answer 49

yes we're done :)

Answer 50

OMG thanks @ganeshie8 you are AMAZING

Answer 51

aww thnks you're sweet :)

Answer 52

Blushing lol

Answer 53

lol
