Question

I have to rewrite these equations in slope-intercept form, am I correct?

-4x + 6y = 18 and 3y + x = 5

Answer 1

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

Answer 2

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

Answer 3

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?

Answer 4

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

Answer 5

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

Answer 6

that's what i meant aaah sorry

Answer 7

Its alright lol

Answer 8

so first just start by adding 4x to both sides

It will come out as \[6y = 4x +18\]

Answer 9

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

Answer 10

simplify
\[y = \frac{ 4x }{ 6 } + 3\]

And you have that answer

Answer 11

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

Answer 12

yup

Answer 13

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!

Answer 14

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!
