## pokiedokie one year ago I have to rewrite these equations in slope-intercept form, am I correct? -4x + 6y = 18 and 3y + x = 5

1. PokieDokie

for -4x + 6y = 18 I rewrote it to: y = 18 - 4x + 6y

2. PokieDokie

I'm about 99.9% sure I got that incorrect, can someone help?

3. ckallerid

It's a bit off. If I remember correctly in slope intercept form you're supposed to isolate the y. Do you know what PEMDAS is?

4. PokieDokie

yes i do, so I solve y first and use PEMDAS?

5. ckallerid

well kinda... You need to be doing both at the same time.

6. PokieDokie

that's what i meant aaah sorry

7. ckallerid

Its alright lol

8. ckallerid

so first just start by adding 4x to both sides It will come out as $6y = 4x +18$

9. ckallerid

Divide 6 to both sides $y = \frac{ 4x }{ 6 } + \frac{ 18 }{ 6 }$

10. ckallerid

simplify $y = \frac{ 4x }{ 6 } + 3$ And you have that answer

11. PokieDokie

oh okay! so we leave the fraction as is then?

12. ckallerid

yup

13. ckallerid

same with the other one. 3y + x = 5 Subtract x from both sides 3y = -x + 5 Divide 3 to both sides y = -x/3 + 5/3 You can't simplify on this one sooooo that's the answer!

thank you so much!! i tried the 2nd one and ended up getting it correct like you said. I understand it much better now ty!
