## sammy5592 Group Title –3x + 2y = 8 change to slope intercept form show all steps. 2 years ago 2 years ago

1. Bidoof

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

2. sammy5592

2y=11

3. Bidoof

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

4. sammy5592

ok so?

5. Bidoof

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

6. sammy5592

how do you do that

7. sammy5592

@hal_stirrup

8. sammy5592

can you help ?

9. hal_stirrup

Don't you know how to manipulate equations ?

10. sammy5592

no

11. hal_stirrup

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.

12. Bidoof

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

13. Bidoof

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

14. sammy5592

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

15. hal_stirrup

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

16. sammy5592

idkk :(

17. hal_stirrup

18. sammy5592

divide?

19. hal_stirrup

divide what?

20. sammy5592

y and 2?

21. hal_stirrup

nop

22. sammy5592

dammit

23. hal_stirrup

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

24. sammy5592

darn idk

25. sammy5592

Sh!+

26. hal_stirrup
27. hal_stirrup

its easy . trust me. ;)

28. sammy5592

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

29. hal_stirrup

no sorry NOT allowed . website rules.

30. sammy5592

rules are mint to be broken

31. sammy5592

JK

32. hal_stirrup

no not here and not for me.

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

34. abigail2010

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

35. sammy5592

Thank you very much

36. abigail2010

You're welcome!
