Question

What is the slope-intercept form of the function that contains the points (5, 6) and (9, 14)?

y = x +

@bruhhh

Answer 1

Okay so this has the same idea as the last one, except the slope isn't given.
So you've gotta calculate it by using this:
\[\frac{ y2-y1 }{ x2-x1 }\]
Plugging those in will make it\[\frac{ 14-6 }{ 9-5 }\]
So evaluate your slope first, tell me what you get :)

Answer 2

I'm also doing this do you mind if I stay and learn too cause I've had similar questions and im not good at them

Answer 3

8/4 @bruhhh and for you @shinebrightlikeadimon no i don't mind you can stay

Answer 4

hey @TeenWolfGirl im gonna help you one sec

Answer 5

@shinebrightlikeadimon yeah i dont mind either :) haha

So your slope can simplify even more, whats 8/4?

Answer 6

ok and @bruhhh why did i get a medal?

Answer 7

4/2 and if you simplify that you get 2/1 which = 2

Answer 8

i gave you one ^.^ so since the slope is 8/4 m = 2?

Answer 9

Lol whaaa, I don't even know how to give medals so no idea

Answer 10

oh!!! @shinebrightlikeadimon gave me one i still don't know why?

Answer 11

why in the world am i getting a medals i still don't know the answer

Answer 12

Yesss @shinebrightlikeadimon

So now you guys need to use point slope form using one of the ordered pairs, which is:
y-y1=m(x-x1)
Plugging in either ordered pair will get you the same answer but I'm gonna use (5,6) since the numbers are smaller lol
So it will look like:
y-6=2(x-5)

Do ya'll know what to do from there to get it in y=mx+b form?

Answer 13

i only got 2

Answer 14

*looks at @bruhhh*

Answer 15

no

Answer 16

wait do you simplify ?

Answer 17

yea that's how you get the answer

Answer 18

so simplify and add 6 to both sides?

Answer 19

*smiles* sweetheart i'm not that smart no mean to be rude but if i was i wouldn't need this website to teach me

Answer 20

Yes! @shinebrightlikeadimon
@TeenWolfGirl do you get that? It's the same thing we did in the last problem, I'll type the example in a sec

Answer 21

thnx ? @TeenWolfGirl and great cause i wasn't sure @bruhhh

Answer 22

So we've got y-6=2(x-5)
You've gotta distribute the slope (2) and that's what we mean by simplify, so it'll look like
y-6=2x-10
Then add the 6 to both sides and what's your answer @TeenWolfGirl :)

Answer 23

@shinebrightlikeadimon no prob! :)

Answer 24

y=8x-16

Answer 25

y - 6 = 2x - 10
+ 6 + 6
y = 2x - 4 ?

Answer 26

the slope is 2 not 8 @TeenWolfGirl

Answer 27

how i though you add 10+6 not subtract?

Answer 28

Sorry, I've gotta get in the shower and go after this one but I'll be on later if you need more help.

But yeah. @shinebrightlikeadimon is right.
You are adding 6, but the equation says the 10 is negative. So it's -10+6 :)

Answer 29

oh!

Answer 30

so its y=2x+2?

Answer 31

Here use a calculator for that type of addition if you need it, it'll help a ton! -10+6 is -4
So it's y=2x-4
Make sense?

Answer 32

hehe yea forgot about that thx

Answer 33

geez i want to give both medal but i can only give one @bruhhh can you give @shinebrightlikeadimon a medal?

Answer 34

Lol okiedoke, I'll be on later ^.^
Good luck!

Answer 35

thank you

Answer 36

to both of you

Answer 37

np and thanks you both

Answer 38

hehe np
