Question

What is the y-intercept of the equation 2x + 3y = 12?

-2/3
4
6
12

Answer 1

Hey set it up in y = mx+b (b = y - intercept) format that way you will be able to see the y - intercept clearly.

Answer 2

So solve for y, do you know how to do that?

Answer 3

yes

Answer 4

do it

Answer 5

ok

Answer 6

2x + 3y = 12

start by subtracting 2x both sides

Answer 7

What do you mean

Answer 8

u - 2x from 12 =10 2x - 3y and u get 1y

Answer 9

remember this in algebra :
you can't add/subtract apples and coconuts

Answer 10

2x + 3y = 12

subtracting 2x both sides :
2x + 3y = 12
-2x -2x


you should get :
3y = 12 - 2x

Answer 11

ok

Answer 12

but "y" still has that 3 attached to it
how to get rid of that 3 ?

Answer 13

Often for these algebraic problems to move something to the other side we use the opposite operation of what already exists, so since there's a 3 attached to the y, which means it's being multiplied.

What can we do to get rid of the 3?

Answer 14

Don't worry about being wrong, say what ever is on your mind it's ok

Answer 15

c

Answer 16

its b

Answer 17

Answer 19

I've been up for 24+ hours so that's my queue xD

Answer 20

i did not delete your things

Answer 21

I know I did

Answer 22

ok

Answer 23

hey just one moment

Answer 24

Let me do the algebra quickly to...

Answer 25

4 is correct, but may i know this :
when you said below, what were you thinking ?

Answer 26

3y=12-2x
y=(12-2x)/3
y= -2x/3+4 works out

Answer 27

Ganeshie is asking you what you meant by your comment here

Answer 29

o ok

Answer 30

yes you @ltj1234

Answer 31

idk

Answer 32

The 10 I think you were trying to subtract 2x from 12, but you can't do that since there is a variable (x)

Answer 33

sure you know it ^

Answer 34

when you have `12 - 2x`,
you leave it like that

you can't say that equals `10` because they are not "like terms"

nevertheless, it was really a very good attempt from your side! keep it up!

Answer 35

ok

Answer 36

For sure, good job @ltj1234

Answer 37

thanks
