help please

OpenStudy (foxythepirate0984):

OpenStudy (smartyprincess):

please tell me what you think it is and we can go from there :)

OpenStudy (smartyprincess):

@Foxythepirate0984 what do you think?

OpenStudy (foxythepirate0984):

well thats the thing idk what it is

OpenStudy (boldjon):

yo foxy my man, what do u think it is bro

OpenStudy (boldjon):

just give a guess

OpenStudy (smartyprincess):

we can't give direct answers but we can explain how to get them :)

OpenStudy (smartyprincess):

yes, give it a guess

OpenStudy (boldjon):

u might be right i'llcheck for u

OpenStudy (foxythepirate0984):

couldnt you PM me? if not then i would guess d

OpenStudy (smartyprincess):

@boldjon you are right

OpenStudy (smartyprincess):

ok

OpenStudy (smartyprincess):

lets see

OpenStudy (smartyprincess):

d is -9/5

OpenStudy (smartyprincess):

hold a seck i am going to figure this out

OpenStudy (anonymous):

Remember a linear equation setup is y=mx+b

OpenStudy (smartyprincess):

yes

OpenStudy (smartyprincess):

ok

OpenStudy (boldjon):

could it be b

OpenStudy (boldjon):

b

OpenStudy (smartyprincess):

I am still doing it

OpenStudy (smartyprincess):

sure

OpenStudy (smartyprincess):

I think so

OpenStudy (boldjon):

yup it's B

OpenStudy (boldjon):

just checked, want me to explain

OpenStudy (smartyprincess):

wait a sec i am still trying to figure this out :)

OpenStudy (boldjon):

lol take ur time gurl

OpenStudy (foxythepirate0984):

while that maybe bold can help me with more questions

OpenStudy (anonymous):

Okay... Remember you need to set up your equation in the format y=mx+b, and do that by making it an equation. Once there, parallel lines have the exact same slope.

OpenStudy (smartyprincess):

2x+5y=10 => 5y = -2x+10 => y = (-2/5)x+2 Slope of this line is -2/5; Line parallel to the above line will have the same slope. y = (-2/5)x+c => (-1) = (-2/5)(-2) + c => -1 = 4/5 + c => c = -1-4/5 = -9/5; Answer: Required equation in slope form is y = (-2/5)x = 9/5; In standard form: 2x+5y = 9;3x-x+2=4 so what do you think the answer is after this, I did my work on comput. so copy and paste from my power point :) it is faster than typing everything again :)

OpenStudy (anonymous):

I've got B as well,@boldjon

OpenStudy (smartyprincess):

me too

OpenStudy (smartyprincess):

may i please have a medal, and if not it is allright

OpenStudy (smartyprincess):

thanks!

OpenStudy (smartyprincess):

I will give you all one as well

OpenStudy (foxythepirate0984):

^_^ can you help with more?

OpenStudy (anonymous):

So do u understand how we got B @Foxythepirate0984 ?

OpenStudy (smartyprincess):

sure

OpenStudy (smartyprincess):

a couple cause got to get back to my history

OpenStudy (foxythepirate0984):

OpenStudy (smartyprincess):

thanks

OpenStudy (smartyprincess):

@boldjon when you said this lol take ur time gurl thanks!

OpenStudy (boldjon):

k ^_^ and i don't get a medal bruh?

OpenStudy (foxythepirate0984):

._.

OpenStudy (smartyprincess):

I gave you one?

OpenStudy (boldjon):

lol the answer is D cuz the y intercept is the last number and the x intercept is the number after the equal sign

OpenStudy (foxythepirate0984):

thank

OpenStudy (boldjon):

Anytime ^_^

OpenStudy (smartyprincess):

o find the slope of an equation - we need to convert the equation in the slope-intercept form y = m*x + c and compare values of `m` and `c` so that we can get the value of slope and the `y` intercept `m` is the slope of equation and `c` is the y-intercept So converting the given equation in the slope-intercept form we get y = 0*x + -1 On comparing we get values of `m` = 0 and `c` = -1 That means the line has a slope 0 and the y-intercept is -1 Slope 0 means line is parallel to x-axis

OpenStudy (smartyprincess):

so yes d

OpenStudy (foxythepirate0984):

one more.

OpenStudy (boldjon):

throw as many as u want

OpenStudy (smartyprincess):

ok

OpenStudy (boldjon):

so what is it

OpenStudy (smartyprincess):

yes

OpenStudy (foxythepirate0984):

and the 2ollux iis goiing to be in thi2 one

OpenStudy (smartyprincess):

ok

OpenStudy (boldjon):

uh...what?

OpenStudy (foxythepirate0984):

OpenStudy (boldjon):

k thanks hold up

OpenStudy (foxythepirate0984):

can you 2olve thii2?

OpenStudy (smartyprincess):

ok let me see

OpenStudy (anonymous):

Okay, take 14x + 6y = 3 For a parallel slope.

OpenStudy (smartyprincess):

1. slope of this line is 4 and the slope of the perp line is alway the inverse negative -1/4 option c 2. 5x 2y = 11 2y = -5x + 11 y = -5/2 + 11/2 slope is -5/2 option B 3. put in the values for x and y and see if they equal 11 1,2 3(1) + 7(2) = 17 nope 0,4 3(0) + 7(4) = 28 nope 6,1 3(6) + 7(1) = 25 nope 0,4 3(0) + 7(4) = 28 nope

OpenStudy (foxythepirate0984):

2o iit2 b?

OpenStudy (boldjon):

OHHHHHHthe answer is D cuz X is 6 an Y is -1 if u plug them in for x and y you'll get 11

OpenStudy (foxythepirate0984):

oh ok

OpenStudy (smartyprincess):

yes

OpenStudy (foxythepirate0984):

ii got a C c:

OpenStudy (smartyprincess):

any more?

OpenStudy (foxythepirate0984):

thanks for helping

OpenStudy (smartyprincess):

welcome :)

OpenStudy (boldjon):

lol i think i'm not getting any profit from this, other than the enjoyment, haven't even 1 medal

OpenStudy (boldjon):

well ur welcome night

OpenStudy (anonymous):

Hopefully you understand the topic! Have a good evening!

OpenStudy (smartyprincess):

you too!

OpenStudy (smartyprincess):

happy holidays!
