Question

systems help!

Answer 1

The two lines intersect at the point (-2, 1).

Answer 2

thanks for coming
!

Answer 3

y=mx+b use that formula use it twice and make the y and x equal but vary the m and b

-2=m_1*1+b_1
-2=m_2*1+b_2 that ought to work i think.

Answer 4

i dont understand!

Answer 5

make the y and x equal to (-2,1).

Answer 6

from a point there could be infinitely many lines can pass through

Answer 7

so it could be so just write y=mx+c and put y=1 and x=-2

Answer 8

so :1=m(-2)+b

Answer 9

?

Answer 10

it could be anything like y=x+3

Answer 11

oh okay

Answer 12

i need another equation!

Answer 13

You need another equation?

Answer 14

Or another explanation?

Answer 15

i need to label line and bi have line a which is y=x+3 now i need another equation!

Answer 16

need to label line a and b and i have line a already

Answer 17

let me scan the paper for you so it will help u okay

Answer 18

Wow, I was just about to ask you! :) Okay! :)

Answer 19

sorry cofee fell on it butll make sure ill show u just give me 2 minutes okay! :)

Answer 20

Sure! Take your time. :)

Answer 21

i think this is it!

Answer 22

the second questions says what is the quation of each line u drew in problem 5? explain how u wrote each equation!

Answer 23

Hmm, just a sec, Tahmina. I must go calm my dog down (she's scared of thunder lol). But I have reviewed your question. :)

Answer 24

okay but i need u so please hurry! i have to got to bed its kinda getting late and i have school and i need to get enough sleep! thanks!

Answer 25

:)

Answer 26

what happened? :(

Answer 27

u suddenly were typing then poof ur gone oh tafkas i really need ur help please!

Answer 28

yeah theres u go ur typing again :) yay! :)

Answer 29

Poor dog! :) Arrgh...

Pick any two points that you made, then use this calculator:

It will also show you the steps.

Answer 30

sorry about that. :/

Answer 31

im bad at this i tried this kind athying! sorry about that!

Answer 32

The points on your line that I would use are (-2, 1) and (0,3)

Answer 33

ONce you plug in those values, it will create the equation that you need.

Answer 34

but i dont have another coordinates can u show me im confused and tired :(

Answer 35

here, I plugged it in for you:

http://www.miniwebtool.com/slope-intercept-form-calculator/?x1=-2&y1=1&x2=0&y2=3

Answer 36

thansk! i need line b now

Answer 37

please!

Answer 38

Okay, line b must be parallel. do point slope form:

y - y1 = m(x - x1)

and plug in your values:

y - (1) = 1(x - (-2))

y - 1 = x + 2
y = x +3

since your slope is one, you can have literally anything for your next line:

y = x + 5

got it?

Answer 39

oh okay! i was gonna ask u that!

Answer 40

sam slope but difrent y itercep tno wits coming back to me ohhh

Answer 41

Great! So you think you got it, now?

Answer 42

yeah! thanks! for all ur help1

Answer 43

Awesome! You're welcome, Tahmina. You know I don't mind helping you. :) Oh, there's the dog again... :)

Answer 44

and the lightining?

Answer 45

Ha ha, it freaks her out. She's not a chihuahua, but she shakes like one when she hears thunder XD

Answer 46

can u help me with another problem!?

Answer 47

hello?

Answer 48

:)

Answer 49

Let's get rid of "y." The second equation can be simplified. Divide all those terms in the second equation by 4:
2x+3y=2
(24x+4y=12)/4 --> new equation: 6x + y = 3

NEW SYSTEM:
2x+3y=2
6x + y = 3

multiply second equation by -3 to get rid of the y terms.

NEW SYSTEM:
2x+3y=2
-18x -3y = -9
____________________________________ (add the equations)
-16x = -7


x =.......

Do you understand this?

Answer 50

so the answer is c?

Answer 51

thanks!

Answer 52

tgt bye ! have to pray ans take a shower see u next time!

Answer 53

Yes! :) See you next time! :D
