Question

What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)

Answer 1

What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)

Answer 2

first find the slope
slope,m = change in y / corresponding change in x

Answer 3

y=-3x+28

Answer 4

what do you get for the slope?

Answer 5

@Nnesha the question said in point-slope form,

Answer 6

that's not what I got, i have to check mine

Answer 7

@destinyishot what is the slope?

Answer 8

What is the equation of the line, in point-slope form, that passes through the points (-7, -10) and (-6, -8)

Answer 9

(9,1)-> x1,y1 & (4,16)->x2,y2
First find the slope which is by m=y2-y1/x2-x1
=16-1/4-9

m =-3

Equation of the point-slope given by y-y1=m(x-x1)
y-1=-3(x-9)
y-1=-3x+27
y=-3x+28

Answer 10

(-7, -10) and (-6, -8)

m=2 and equation is y=2x+4

Answer 11

y + 10 = -2(x + 7)
y - 10 = -2(x - 7)
y + 10 = 2(x + 7)
y - 10 = 2(x - 7)
these are the choices i understand the m equals 2 but ....... so is it c or d

Answer 12

d

Answer 13

Hey, first understand the question and then try to learn it and I swear math is gonna be very easy but the option for the above quest is c :)

Answer 14

Do you like want to understand the concept, I can help you with that :)

Answer 15

its -8+10/-6+7 is 2/1 i understand but the second part i feel really blonde

Answer 16

and yes i would i want to learn....

Answer 17

The point-slope form of the equation of the line through (x1, y1) with slope m is
y-y1 = m(x-x1)

Answer 18

It's pretty easy see It's like you gotta use this formula-> y-y1=m(x-x1) and then sub in the values.

y+10=2(x+7)
y+10=2x+14
y=2x+4

Answer 19

What is the equation of the line, in point-slope form, that passes through the points (-3, -1) and (-6, 8)?
so the slope is -3 and im trying the other part

Answer 20

y - 8 = -3(x + 6)

Answer 21

im sorry i just dont understand where you got (x-x1)

Answer 22

Listen first decide which points you're taking as x1,y1 and x2,y2.
m is -3 yes.

And the equation for the point-slope in y-y1=m(x-x1)

The equation is that and then you gotta sub in the values like I've taken x1,y1 as -3,-1

so, y-1=-3(x+3)
y=-3x-8

Answer 23

y + 8 = -3(x - 6)

Answer 24

Listen first, what did you take your x1,y1 & x2,y2 as?

Answer 25

x1 is -3
y1 is -1
x2 is -6
y2 is 8

Answer 26

@studystagram point-slope form is defined above
do not rewrite in slope-intercept form
@destinyishot there are 3 formats for writing the equation of a line

Answer 27

What is the equation of the line, in point-slope form, that passes through the points (-3, -1) and (-6, 8)?
y + 8 = -3(x - 6)
y - 8 = -3(x + 6)
y + 8 = 3(x - 6)
y - 8 = 3(x + 6)

ok heres the question and answers .......i get half of it i know is m equals -3 but now I'm so confused

Answer 28

Okay you've taken it correct so you gotta sub in the values of x1,x2 and NOT X2,Y2. that's what you did there. You gotta do like this-> y-1=-3(x+3)

so, opening up the bracket on R.H.S., y-1=-3x-9
y=-3x-8

Answer 29

Wait, in your question they've taken (-6,8) as x1,y1 so yeah that's correct

so the ans will be, y-8=-3(x+6) which is b

Answer 30

You got it now? You should've given the options before lol so I would've taken the x1,y1 accordingly.

Answer 31

i tryed ..... but yes thank you

Answer 32

@triciaal, I really don't know what you meant by that, but I'm anyway answering by what I interpreted cuz you WILL get the ans in slope intercept form but you can change accordingly for ex- you can write also like y=-3x-8 OR -3x-y-8=0. Either way is correct and you WILL get the marks.

Answer 33

What is the equation of the line, in point-slope form, that passes through the points (-1, 7) and (-2, 3)?
y + 7 = -4(x - 1)
y - 7 = -4(x + 1)
y + 7 = 4(x - 1)
y - 7 = 4(x + 1)

Answer 34

@destinyishot Try and temme what you get the ans for the above question you've just posted and I will cross check with mine. If you don't understand, ask me.

Answer 35

c

Answer 36

It's d. Sign mistake. It's okay, you got the hang of it at least but you gotta be really attentive when there are -ve signs involved.

Answer 37

ok i got it alright new question if your up for it....
What is the slope of the line that contains the points (-3, -2) and (4, -2)?

Answer 38

well thanks anyway studystagram i really am grateful for your help............

Answer 39

it doesn't have the slope the slope is 0

Answer 40

well would you use y2-y1/x2-x1 so it -4/7 right

Answer 41

yes i did but that is no -4

Answer 42

when you put y value -2-(-2) you should got 0

Answer 43

-2-(-2)/4-(-3)
= -2+2/4+3
=0/7
m=0

Answer 44

The slope is 0 as @Nnesha mentioned.

Answer 45

ok did it back ward i think i understand

Answer 46

- 4
undefined

- 4/7

0





wait is it 0/7

Answer 47

these are the answers

Answer 48

It's 0, the ans.

Answer 49

what about undefined

Answer 50

you got -4 bec you did -2-2 instead of -2-(-2)

Answer 51

What is the slope of the line that contains the points (2, 6) and (-1, -6)?
so 4

Answer 52

Undefined is when you divide something by 0.

Answer 53

Yeah the slope is 4. Well done hun! (:

Answer 54

yes good job @destinyishot

Answer 55

@studystagram REPOST
@studystagram point-slope form is defined above
do not rewrite in slope-intercept form
@destinyishot there are 3 formats for writing the equation of a line
so you know 2 of the 3 the third is what the original question asked for
any format will give the same line

1 point-slope
2 slope-intercept
3 standard

Answer 56

What is the slope of the line that contains the points (-2, 8) and (-2, 1)
so its 7/0 this is what you talking about undefined

Answer 57

Yeah, that is undefined. Okay, I'm off to sleep. It's kinda late here :)

Answer 58

ok thank you and from where......

Answer 59

i hope your not some old creepy man in india

Answer 60

Lol. I live in muscat and rest assured I'm a teen girl haha
