Question

–3x + 2y = 8
change to slope intercept form show all steps.

Answer 1

Slope intercept form is y=mx+b
Step 1: Isolate the term with the y variable

Answer 2

2y=11

Answer 3

You can't combine 3x and 8 because 3x has a variable and 8 doesn't

Answer 4

ok so?

Answer 5

It will be 2y=3x+8, but you still have to remove the number attached to y by dividing both sides by that number

Answer 6

how do you do that

Answer 7

@hal_stirrup

Answer 8

can you help
?

Answer 9

Don't you know how to manipulate equations ?

Answer 10

no

Answer 11

then you should go back to basic equations and practice that so you can get this. dont build a house of card . solid maths foundation is key.

Answer 12

You need to divide both sides by 2 to remove the 2 that is with the y variable
If it was a fraction, you would multiply by the denominator to cancel it out

Answer 13

For the other side, simply divide both terms by 2 to get your answer.

Answer 14

2y=3x+8 3x 4y ??

Answer 15

ok . lets say y/2=x solve for x? what operator do you need to use?

Answer 16

idkk :(

Answer 17

think about it.

Answer 18

divide?

Answer 19

divide what?

Answer 20

y and 2?

Answer 21

nop

Answer 22

dammit

Answer 23

ok if i say to you make y/2 to y what do you have to do. note that y/2 is really \[y\frac{ 1 }{ 2 }\]

Answer 24

darn idk

Answer 25

Answer 27

its easy . trust me. ;)

Answer 28

Can you just please give me the answer? this is the last question.

Answer 29

no sorry NOT allowed . website rules.

Answer 30

rules are mint to be broken

Answer 31

JK

Answer 32

no not here and not for me.

Answer 33

Alright sounds like people are harsh over here. The slope formula is mx+b=y
So thus you need to get the equation above like it..
-3x+2y=8
First, I would add 3x to both sides. So it's like 3x+(-3x) +2y = 8 -3x, the 3x's on the left will cancel. So you will get 2y = 8-3x.
So now it's almost in the mx + b =y form you have have the extra 2 in the 2y
So now you need to divide both equations by 2 to eliminate the 2y.
Thus it would be like... 2y/2 = 8-3x/2 or you can write it like y = 8/2-3x/2... finally the 8/2 can be reduced to 4
SO finally the answer would be...
y = 4 - 3/2x

Answer 34

actually time out let me fix that.. it won't be -3/2x it should be +3/2x
it will actually be y = 4 + 3/2x

Answer 35

Thank you very much

Answer 36

You're welcome!
