Answer 1

@Preetha can you help me??

Answer 2

@amistre64

Answer 3

hia again

Answer 4

whats our slope? and hi

Answer 5

idk yet because idk what numbers to use

Answer 6

y=mx+b

Answer 7

the line goes thru 2 readily seen points. use them

Answer 8

what are the points?

Answer 9

oh (1,3) and (10,11)

Answer 10

9,11 but yeah

Answer 11

oh ya lol

Answer 12

so i have to do Y1 - Y2
------
X1 - X2

Answer 13

you prolly could yeah :)

Answer 14

is the slope 1

Answer 15

yep, and when x=0 what would you gander the y intercept is from the chart?

Answer 16

uh 0 i think so b= 0

Answer 17

so y=mx+b = y= 1 x + b

Answer 18

y=1x+0

Answer 19

the line is not crossing the y axis anywhere near y=0 ...

we can do this the hard way if you want ..

given a point (a,b) and a slope, m: we can construct the "point-slope" form if a line as:

y-b = m(x-a) and then conform it to your particular setup as

y = mx -ma + b

keeping in mind that this b is not your b

Answer 20

or we could just adjust it by the point

1,3 is on the line sooo


y = mx + b
3 = 1(1) + b ; what is b?

Answer 21

i think 1

Answer 22

I forgot how to find the y-intercept

Answer 23

3 = 1 + 1 ... not quite right

Answer 24

oh 2 lol

Answer 25

maybe

Answer 26

you find the y intercept (the point it cross the y axis) by looking at the chart or filling in the values

Answer 27

3 = 1 + b, so b = 2 yes

there are many ways to approach this.

Answer 28

ya i feel dumb

Answer 29

thank you again theirs your medal

Answer 30

good luck :)

Answer 31

do you think you can help me with this one or check it

Answer 32

maybe

Answer 33

ok

Answer 34

Based on the linear model, what is the possible value of Variable K when Variable J is 2?

Answer 35

and your solution would be what?

Answer 36

i got 27

Answer 37

is that right??

Answer 38

i dont see how you would even get that

find j=2, follow it up till you hit the line, then move left to find its k value

Answer 39

what is the value of k at the point?

Answer 40

k=j+2

Answer 41

oh is it j=k+2

Answer 42

no, it exactly like i instructed you to do ...

Answer 43

02

Answer 44

20

Answer 45

yeah ... its 20

Answer 46

2,20

Answer 47

nvm its just 20 right

Answer 48

when j=2, the line suggests k=20

Answer 49

so the answer is 20 correct

Answer 50

yeah ... its 20, again

Answer 51

ok thank again ^_^ i wish i can give you 100 metals thx

Answer 52

goodluck ...
