Question

What is the slope-intercept form of the function that contains the points (6, 2) and (4, 8)?

Answer 1

@sleepyjess

Answer 2

@sleepyjess plz come help

Answer 3

as i said last night, we need to find the slope first
do you know how to do that?

Answer 4

not reallly

Answer 5

you have 6, 2 as point 1 and 4, 8 as point 2
\(\dfrac{y_2-y_1}{x_2-x_1}\) 6, 2 = \(x_1,~y_1\) 4, 8 = \(x_2,~y_2\)

Answer 6

then wat happens after that to find the answer

Answer 7

substitute the points i gave you into the formula

Answer 8

yea

Answer 9

@sleepyjess i didnt get the answer i dont get hoiw to substitute it

Answer 10

show me what you did to substitute the numbers
i gave you the points and what the point represented

Answer 11

but how do i susbitute

Answer 12

use 6 as \(x_1\) 2 as \(y_1\) 4 as \(x_2\) and 8 as \(y_2\)

Answer 13

@sleepyjess it has to be like this y = x +

Answer 14

i know but to get that we need to get the slope

Answer 15

so wat would be the sope plz

Answer 16

just put in the numbers to the formula i gave you

Answer 17

sooo 6,2 is 1x i think

Answer 18

@sleepyjess

Answer 19

@sleepyjess is this it

Answer 20

\(\dfrac{8-2}{4-6}\)

Answer 21

so 6x -2

Answer 22

@sleepyjess so 6x -2

Answer 23

no your slope is \(-\dfrac{6}{2}\) which can be simplified to -3
now we have -3x+?
can you find the y intercept with that information?

Answer 24

um 16

Answer 25

@sleepyjess is is 16 or -16

Answer 26

going down 2 for x and up 6 for y
point 3 is 2, 14
point 4 is 0, 20

which point is the intercept?

Answer 27

it says im typin bt i9m not

Answer 28

no which point has the x value as 0? 3 or 4?

Answer 29

its fine it does it for me too

Answer 30

ummm 8

Answer 31

o 4

Answer 32

is it 4

Answer 33

i said 4 not 8

Answer 34

yes point 4 has an x value of 0 what is the y value for point 4?

Answer 35

@sleepyjess u still here

Answer 36

um 20

Answer 37

yes so your equation is y=-3x+20

Answer 38

20

Answer 39

@sleethx i understand that now i got diff. kind of quesion kjind of diff.

Answer 40

@sleepyjess

Answer 41

What is the slope-intercept form of the function described by this table?


x 1 2 3 4
y 1 −2 −5 −8





y = x +

Answer 42

@sleepyjess srry abought that lag plz come help me

Answer 43

sorry my computer decided to randomly restart

Answer 44

hay man can u help me out with that first question like what was the answer it was not that clear
