I need help with this wkst https://docs.google.com/viewer?a=v&pid=sites&srcid=c2R1aHNkLm5ldHxtcnMtcm9ic29uLXMtd2VicGFnZXxneDoyNmRkOGMyNGRiZTU1ZGQ

Answer 1

which question ?!

Answer 2

remember to find the y intercept look where the line intercets the y axies

Answer 3

all of them

Answer 4

can you help me with y intercept the slope and the equation though

Answer 5

1-4 first

Answer 6

Slope = (-2/3)
Y-int = 2
Equation : "y = (-2/3)x + 2"

Answer 7

for the first one?

Answer 8

can you do the second one

Answer 9

no this is no.4

Answer 10

Ok, i'll solve you the second one

Answer 11

wait

Answer 12

can you solve 1-4?

Answer 13

No, you have to do them by yourself....i'm just helping.

Answer 14

i'll solve the second

Answer 15

2-

Slope = 1
Y-int = 0
Equation: y=x

Answer 16

how did you do it?

Answer 17

as you can see, the st.line is passing throw (0,0)
this means that the y-int = 0


So the equation is "Y = aX"

choose any two points on the graph and substitute with them in the equation

let it be (2,2) for example:

2 = a * 2

so a = 1

so the equation is : "y = x"

Answer 18

can I solve one then see if I get it right?

Answer 19

yeah , sure

Answer 20

thanks

Answer 21

wait the y-int that I learned was you always have to put 0 then the number

Answer 22

is the answer 1, (0,1), y=x+1?

Answer 23

for number 1

Answer 24

No, that's wrong answer

Answer 25

try again

Answer 26

you can get they y-int by letting x=0

Answer 27

y-int is the point of intersection between the St.line and the y-axis

Answer 28

is the slope correct?

Answer 29

what is not correct?

Answer 30

ohh I see

Answer 31

no it's not

Answer 32

is the slope -4, the y-int (0, 3 1/2), and the equation y=-4x+ 3 1/2?

Answer 33

actually , the graph is not so clear , so i considered the y-int as (0,3)

Answer 34

is everything else correct?

Answer 35

the answer of no 1 will be:

Y-int = (0,3)
Slope = -3

Equation : "y = -3x+3"

*of course this answer is by considering the y-int is 3 not 3.5 or else

Answer 36

ok

Answer 37

let's keep going!

Answer 38

number 3

Answer 39

will you solve it ?!

Answer 40

yes

Answer 41

and you can check

Answer 42

Ok, go on

Answer 43

ok

Answer 44

can you tell me the answer so I can check?

Answer 45

no , you tell me your answer

Answer 46

ok

Answer 47

slope is 1
y-int is (0,-2)
equation is y=1x-2

Answer 48

you got the y-int right, but you mistaken the slope

Answer 49

it's rise over run

Answer 50

found it

Answer 51

nope I haven't

Answer 52

how do you do slope? cause I know it's rise over run?

Answer 53

yes it's, but in mathematical words...it's change y over the change of x

so you just pick any two points

e.g : (1,0) & (0,2) [i chose them to only ease the calculations]

so the slope = (\[(2-0) \over (1-0) \]
which is equal to -2

Answer 54

sorry it's (0-2) not (2-0)

Answer 55

is that the answer to number 3 for the slope or is that an example?

Answer 56

yes it's for no. 3
