Question

can i get help with x+2y=2

Answer 1

What are you asked to do?
Solve for y?

Answer 2

y=mx+b

Answer 3

Put it in that form?
Do we need to graph it afterwards? :)

Answer 4

i no i need to get y by its self but im stuck

Answer 5

yes and i dont no how to graph it

Answer 6

\[\Large x+2y=2\]Hmm ok let's start by getting x to the other side.
So we'll `subtract` x from each side to keep things balanced.\[\Large x\color{royalblue}{-x}+2y=2\color{royalblue}{-x}\]
See how the x's will cancel on the left side of the equation? x-x=0.\[\Large 2y=2-x\]

Answer 7

From here, we'll multiply both sides by 1/2.
`Multiplying by 1/2 is the same thing as dividing by 2.`

\[\Large \frac{1}{2}\left(2y\right)=\frac{1}{2}\left(2-x\right)\]The 2's will cancel on the left side,\[\Large \frac{1}{\cancel2}\left(\cancel2y\right)=\frac{1}{2}\left(2-x\right)\]Giving us,\[\Large y=\frac{1}{2}\left(2-x\right)\]
Are you able to see the math code ok?
It should be nice pretty math equations :O

Answer 8

So we've successfully gotten our equation in terms of y=.
But we need to clean up the right side so we can easily identify our `m` and `b`.

Answer 9

Where you at jen? +_+ confused?

Answer 10

do you need help ?

Answer 11

i get it alittle bit

Answer 12

x + 2y = 2
subtract x from both sides
2y = -x + 2
now divide by 2 to get x by itself
y = -1/2x + 1

Answer 13

its not as pretty as zepdrix's...

Answer 14

lol :) i showed too many steps, maybe confusing that way.

Answer 15

ok i got the 1 and the y annd now i see how to get the -1/2x thanks

Answer 16

ok how do i find out what the x and y is bc i dont get how to do that

Answer 17

you mean by graphing ?

Answer 18

yes sorry

Answer 19

you probably need zepdrix for this because I am not the best at graphing...all I know is that the 1 is the y intercept (plot that on the y line. And the slope is -1/2. Rise/run. So from the 1 on the y line, go down one, and to the right 2, then down one, and to the right 2. You really might need zepdrix.

Answer 20

ok thanks

Answer 21

I think to find the x intercept, you need to sub in 0 for y.
y = -1/2x + 1
0 = -1/2x + 1
1/2x = 1
x = 1/2
I think

Answer 22

Looks good besides your last step there :)
From 1/2x=1, we would multiply both sides by 2 right?

Answer 23

oh....your right

Answer 24

So that gives us a couple of points we can plot, We can draw a straight line through those points then.

(0,1) and (2,0)
