Desmos is a great online graphing tool, but its not a good idea to become too dependent on it.

- anonymous

im not suppose to graph it

- DDCamp

Let's start by finding the midpoint using the midpoint equation(s):
\[x = \frac{x_1 + x_2}{2} \\ \\y = \frac{y_1+y_2}{2}\]

- anonymous

i need to find point B using the distance formula or midpoint

- anonymous

Ok !

- anonymous

(1,4) is the midpoint

- anonymous

and 10 is the distance

- anonymous

yeah lol i got that already

- DDCamp

OK. good!

- DDCamp

For the part where you "use distance to justify your answer," find the distance between the two endpoints, then find the distance between an endpoint and the midpoint. If the second distance is half the first, then you probably got the midpoint right!

- anonymous

okay but what is point B?

- anonymous

yo @Robert136 come help us bruuh

- anonymous

Think *brian*

- anonymous

what grade u in @cali16

- anonymous

just started 12th today

- anonymous

DANG thats why i cant get this

- DDCamp

*doh*
I read the question backwards, sorry.

- DDCamp

First, to find B, let's find the change in x coordinates between A and M.

- anonymous

like the distance??

- DDCamp

Yeah, like the distance but just in the x direction.

- anonymous

yeah

- anonymous

dang u fast bruuh @DDCamp

- DDCamp

|dw:1439946324486:dw|

- anonymous

Yeah bruuh thats what i got so u got this right cuz i got this girl on my back man

- anonymous

so do you add them up to get B?? for the midpoint i got (1,4)

- anonymous

see yall GL @cali16 hope u understand it

- DDCamp

So M is the midpoint between A and B, but we already know A and M.
Finding the midpoint between A and M would be finding this point:|dw:1439946627534:dw|

- DDCamp

What we need to do is find what B has to be so that M actually is the midpoint.

- DDCamp

I misread the question the first time and might have accidentally given you some bad hints.

- anonymous

okay so whats the equation do i need to set up

- DDCamp

Instead of an equation, answer this question:
To get from A to M, you have to move left ___ units and up ___ units.

- anonymous

oh okay

- anonymous

u still need help

- anonymous

?

- anonymous

yea

- anonymous

okay what u dont understand ill try to hlp

- anonymous

i dont understand what equation to set up to get B

- anonymous

the question ask for the distance formula

- anonymous

i did

- anonymous

i did that the distance is 10

- anonymous

ok

- anonymous

give me a sec let me think

- anonymous

is this a multiply choice

- anonymous

@cali16

- anonymous

lol fr bruuh this stuff hard

- anonymous

is it multiple choice

- anonymous

no its not multiple choice

- anonymous

*smh* this might take some time and prayers lol

- anonymous

graph A and M

- anonymous

@cali16

- anonymous

@hype.child she said u dont need to graph it cuz i tried that already graphing it

- anonymous

u will it will help find B

- anonymous

thats why i was saying bruuh

- anonymous

lol you dont graph for this problem your suppose to find it using formulas

- anonymous

lol okay i got u

- anonymous

lol im from duval too

- anonymous

lol yeaa DDUUVVAALL

- anonymous

what school do you go too

- anonymous

UH-OH

- anonymous

Paxon

- anonymous

Wbu

- anonymous

oh by commonweath lol i go to victory christian academy

- anonymous

nahh Paxon By jwj

- anonymous

lol

- anonymous

lol

- anonymous

well ill just get this question wrong on my hw lol or ill ask my teacher before class or something thanks everyone for trying

- anonymous

i was solving it

- anonymous

and how ur school start early

- anonymous

lol oh okay sorry well take your time

- anonymous

i just started today and because its private

- anonymous

oo lol dang

- anonymous

bruhh what i started school monday last monday

- anonymous

start school next monday

- anonymous

df

- anonymous

how did u get 10 for the distance formula

- anonymous

@cali16

- anonymous

@cali16

- anonymous

i plugged in the 2 sets of parenthesis into the distance formula

- anonymous

i didnt get 10

- anonymous

myb i did the wrong formula

- anonymous

\[\sqrt{(-3-5)^2+(7-1)^2}\]

- anonymous

work it out

- anonymous

thats how i got 10 im just showing you lol

- anonymous

-3-5)^2+7-1
-8 6

- anonymous

is that what u got at first

- anonymous

yes now square both so you get 64+36 which is 100 the square root of 100 is 10

- anonymous

yes

- anonymous

lol i understand that i just dont get how tf am i suppose to find B with this information lol

- anonymous

lol omg ! im not knocking us skillz @hype.child but ask this kid name @Robert136 he's an human calculator

- anonymous

ur*

- anonymous

lol

- anonymous

what math u takin @cali16

- anonymous

calculus

- anonymous

bruhhhhhhhh calculus i havent evn reach that yet lol

- anonymous

yall blowing up my notification like chill df out
