Solve for y.
y = -3x + 1
y = -3x - 1
y = 3x - 1

Answer 1

Rearrange for y, basically.

Answer 2

y = -3x - 1

Answer 3

Or, let Eric give the answer. Corey will totally learn this way.

Answer 5

step 1.
add -3x to both sides..
and you'll get:
\[\LARGE \underbrace{3x-3x}_{\text{This is 0 }}+y=1-3x\]
so...
\[\LARGE \cancel{3x}-\cancel{3x}+y=1-3x\]
so what do you have?

Answer 6

@Eric_Playsinacoolway that's not correct.

Answer 7

sorry! didn't follow the formula @Kreshnik

Answer 8

No, Corey.

Answer 9

You tell us.

Answer 11

Kreshnik has it perfectly laid out, actually.

Answer 12

@CoreyContini -3+1=1-3
you can chenge places...
and
\[\LARGE y=1-3x\]
what can you get?? :)

Answer 13
