Question

Write the equation of the line that passes through (–3, 4) with a slope of 2 in point-slope form.

y – 4 = 2(x + 3)

y + 4 = 2(x – 3)

y + 3 = 2(x – 4)

y – 3 = 2(x + 4)

Answer 1

point-slope form is y-y1=m(x-x1)

Answer 2

@Luigi0210 @Compassionate guys :)

Answer 3

I am investigating the disappearance of all the cats in the city... my living room is full of cats... that means...

Answer 4

xD ?

Answer 5

Luigi got kidnapped

Answer 6

please helpppp :)

Answer 7

@heather040200 pretty much did our work >.>

Answer 8

You want to use the equation y - y1 = m(x - x1)

Ya' got that foxy mama?

Answer 9

i dont know what to do after that guys i told you i'm kinda dumb when it comes to this hahahaha

Answer 10

Ehh, e-everyone stay calm... because we're all doomed!

Answer 11

No you're not dumb..

Answer 12

D:
@Compassionate what did you do now? -_-

Answer 13

Your points are: (-3, 4) and your slope is 2

y1 = 4
x1 = -3
m = 2

now plug it into y - y1 = m(x - x1)

Answer 14

so the second one would be your answer

Answer 15

We gotta give Heather credit for that.

Answer 16

i knew that thanks heather

Answer 17

No problem :)

Answer 18

i have another one thats similar, wanna try it out while we're all here? it's my last one :)

Answer 19

@heather040200 you might wanna double check your choice.. unless I'm completely losing my math skills

Answer 20

Hoohah! Lets do this foxy mama!

Now remember, I do my best work when I'm being worshipped as a god.

Answer 21

crap @Luigi0210 hahaahhahahaha

Answer 22

I get stupider everyday >.>

Answer 23

im gonna go with heather on this one, sorry Luigi xD you can redeem yourself on the next one

Answer 24

Write the equation of the line that passes through (1, 3) and (4, 4) in standard form.

3x – 3y = –8

x – 3y = –9

x – 3y = –8

3x + y = 9

Answer 25

ya i was gonna say with what compassion gave i would say the second one

Answer 26

>.<

Answer 27

that's my last one guys let's finish strong :)

Answer 28

ok i believe for this one you need to find the slope first
slope is
\[\frac{ y2-y1 }{ x2-x1 }\]

Answer 29

Luigi's always ignored >.>

Answer 30

alright heather

Answer 31

Hey, Sweet jellybean. You smell kinda pretty, wanna smell me? Hoohah!

Use the equation Heather gave you. That's how you find the slope!

Then after you have the slope, plug it into the equation: y - y1 = m(x - x1)

Answer 32

agree with compassionate :)

Answer 33

okay i plugged it in

Answer 34

Okay, can you show me your work sweet-honey.

Answer 35

@Compassionate you keep changing your picture haah

Answer 36

too much work :P

Answer 37

well at least tell what you got LOL

Answer 38

i lied ahahahhaa

Answer 39

I keep finding one that suits my needs! Now that you know I'm pretty, and you're pretty, why don't you say we go back to my place at each other?

Answer 40

Show me the slope you gotta pretty blackmamba mama.

Answer 41

you're a girl?

Answer 42

Of course.

Answer 43

i thought you're name was stephen

Answer 44

Go re-read that again there little lady.

Answer 45

oh alright

Answer 46

but im working out my problem so hold on

Answer 47

You take your sweet time hotty-mitotty.

Answer 48

so the slope is 1/3

Answer 49

i think?

Answer 50

so is it y - 3 = 1/3 (x-1) ????

Answer 51

idk guys

Answer 52

So if the slope is 1/3

That means:
(–3, 4)

y1 = 4
x1 = -3
m = 1/3

Now plug it into y - y1 = m(x - x1)

Answer 53

Haha, hello there

Answer 54

@Compassionate You're a girl since when,LIAR :O

Answer 55

Luigi is back from the grave!

Answer 56

Ha ha, I've always been a girl. Ask Preetha and Boston. Look at my ID. They've seen it.

Answer 57

@Compassionate You told me you're a guy..:(

Answer 58

I also told you that me and my brother use this account. :)

Answer 59

Stop talking to my bro >.>

Answer 60

ok i plugged it in

Answer 61

y-4=1/3(x-(-3)

Answer 62

No you never told me that -______- @Compassionate Stop trolling,We only talk about sketches.

Answer 63

Huh? Sketches? .-.

What are you talking about?

Answer 64

so the answer is A?

Answer 65

@Compassionate Go sleep :) Ttyl.

Answer 66

Good job, Pam! :)

Answer 67

yay finally.

Answer 68

wait guys!!! one more omg

Answer 69

Now- I can view over your work really fast. I am taking your word that you got it all correct and you're solving off of your own logic. If you want, I will go back over your work and check.

Answer 70

yes please.

Answer 71

You're finding the slope through the slope formula of (y2-y1)/(x2-x1) but the equation of a line can be found by using the point-slope formula, given by

y-y0 = m(x-x0)

you already know that m = 1/3 so you have part of the equation, the other part is just one of the points that it passes through, either one will do, but I'll do both just to show you that you end up with the same equation.

So for the first one (1, 3)

y - 4 = 1/3(x - 4) so now we simplify
y - 4 = (1/3)x - 4/3
y = (1/3)x - 4/3 + 4
y = (1/3)x + 2-2/3

so the equation of your line is the above result, your slope is 1/3 which you already know, and your y-intercept is 2 & 2/3 or 8/3. If we were to multiply everything by 3 removing the denominator, your equation would be

3y = x + 8

So now if we use the other point (1,3), the initial equation would look like this

y - 3 = 1/3(x - 1) so now simplifying
y - 3 = (1/3)x - 1/3
y = (1/3)x -1/3 + 3
y = (1/3)x + 2-2/3

which is what we had before with the other point, so now you can see that the point-slope formula will work for any point along the line, and give you the same equation, just as long as you know the slope.

Hope that helps.

Answer 72

so was i right?

Answer 73

Yes, yes you were!

(Ain't Yahoo.Answers lovely!?)

Answer 74

hahahaha! thank you i have one more guys

Answer 75

Anything for a pretty mama like yourself!

Answer 76

Write the equation of the line that passes through (1, 3) and (4, 4) in standard form.

3x – 3y = –8

x – 3y = –9

x – 3y = –8

3x + y = 9

Answer 77

This is the same exact question you just posted :)

Answer 78

oh! hhahahahaah

Answer 79

I love you guys >.>

Answer 80

wait so that one is A?

Answer 81

i love you too luigi @Luigi0210

Answer 82

Ha ha, Pam, you're just adorable. I'm dying over here. You just got the answer to this one not even 2 minutes ago.

Answer 83

Im just confused because the whole time i thought we were working out this question:
Write the equation of the line that passes through (–3, 4) with a slope of 2 in point-slope form.

y – 4 = 2(x + 3)

y + 4 = 2(x – 3)

y + 3 = 2(x – 4)

y – 3 = 2(x + 4)

Answer 84

xD I feel the love

Answer 85

hahahahahha

Answer 86

oh its b nevermind :)

Answer 87

Ha ha, we just worked that out XD This is too great. Someone promote Pam to administrator.

Answer 88

hahahhaa sorry! but i got a 50 on my assignment so im doing it again
