Question

converting standard form to slope-intercept form help

i know how to do it, but I am having troubles with this one

2x + 3y = 1,200

Answer 1

i know we start by subtracting 2x on both sides of the equation to get

3y = 1,200 - 2x

Answer 2

right?

Answer 3

or do we add -2x to get

3y = 1,200 + -2x

Answer 4

@sleepyjess

Answer 5

see what i got is

y = 400 + -2/3x???? is that right

Answer 6

or y = 400 - 2/3x

but with the formula y = mx + b, should it be the addition sign

Answer 7

It should be y = 400 - 2/3x, but switch around 400 and -2/3x to make y = -2/3x + 400

Answer 8

oh I see, so I was right?

Answer 9

yep

Answer 10

So the slope = -2/3 and the y-intercept is 400?

Answer 11

i am in no rush :) get here when you want to help

Answer 12

Oh, sorry, I was trying to get help on a question of my own haha
yes, that is correct :)

Answer 13

that is why i said i am in no rush, i saw ;p and thanks for your help

Answer 14

no problem :)

Answer 15

and in function notation form it's f(x) = -2/3x + 400, correct @sleepyjess

Answer 16

yes

Answer 17

oh so that is how you delete a reply ;p haha i didn't know that

Answer 18

ok! thans for your help
