Answer 1

So whats your answer for #1 ?

Answer 2

x=8
x=-5
y=4
y=-7
?? @ganeshie8

Answer 3

yes! can you also tell which equation represents which line ?

Answer 4

x=8 is horizontal
y=4 is horizontal

Answer 5

hehe to mix things up with this question @ganeshie8 xD

Answer 6

wait i ment sorry to mix hehe

Answer 7

nope, remember this :
for a `horizontal` line, `y coordinate` is fixed, so the equation will be of form :
\[\large y = k\]

Answer 8

oh haha.

Answer 9

try again and see if you can figure out corectly now :)

Answer 10

x=8 vertical
x=-5
y=4 horizontal
y=-7
what does "k" mean when you said y=k?

Answer 11

Yes !
`k` is just any number

Answer 12

oh yay!

Answer 13

next, look at second question

Answer 14

how many blue horizontal lines do you see ?

Answer 15

2

Answer 16

can you write equations to each of them ?

Answer 17

i can try. ok one sec

Answer 18

actually i dont know.

Answer 19

look at the top blue line
it is going through y coordinate 225, right ?

Answer 20

yes

Answer 21

so its equation will be ?

Answer 22

y=225 vertical

Answer 23

@ganeshie8

Answer 24

y=225 horizontal,
ok ?

Answer 25

shoot haha

Answer 26

what about the bottom horizontal line ?

Answer 27

0?

Answer 28

kindof, but 0 is not an equation, 0 is just a number
tell me the equation :)

Answer 29

what do i use instead of 0?

Answer 30

@ganeshie8

Answer 31

equation of horizontal line passing through y coordinate of 0 :
\[\large y= 0\]

Answer 32

i meant that ^^

Answer 33

oh ok so y=0

Answer 34

yes!

Answer 35

yay

Answer 36

see if you can figure ou the equations for blue vertical lines

Answer 37

x=225

Answer 38

yes, you need to tell which line that equation represents also

Answer 39

okay its vertical?

Answer 40

how does that line look ?
vertical/horizontal ?

Answer 41

horizontal

Answer 42

which line are you talking about ?
and do u know the meaning of the words horizontal/vertical ?

Answer 43

vertical is like height and horizontal is like flat

Answer 44

yes, thats right !
can you show me what line ur equation `x=225` represents in your diagram ?

Answer 45

horizontal right

Answer 46

show me in the diagam

Answer 47

what do you mean show you in the diagram?

Answer 48

show me which line your equation `x=225` represents in above diagram ^^

Answer 49

the bottom one

Answer 50

thats wrong,
horizontal line has a fixed `y` coordinate, so the equation will be of form :
\[\large y = k\]

Answer 51

shoot.

Answer 52

but ur equation is `x=225`, so it cannot represent a horizontal line

Answer 53

bottom horizontal line : `y = 0`
top horizontal line : `y = 225`

Answer 54

ohhh okay i see

Answer 55

those are the correct equations for horizontal lines, okay ?

Answer 56

Notice that they are of form :
\[\large y = k\]

Answer 57

okay im starting to get it a little more

Answer 58

so are we done with horizontal lines ?

Answer 59

yes

Answer 60

can we move to vertical lines ?
how manyv ertical lines do u see, and what are they ?
