Question

Help? I will fan and medal. Step by step so I understand :D


1. Put the following equation in slope-intercept form:
3x + 12y = -4
2. Put the following equation in standard form:
6y = -3x + 12

Answer 1

Anyone?

Answer 2

@jim_thompson5910 ??

Answer 3

they want you to isolate y in `3x + 12y = -4`. Do you know how to do that?

Answer 4

Not really good at it :? math is my worst subject

Answer 5

ok the first thing you do is subtract 3x from both sides

3x + 12y = -4
3x + 12y-3x = -4-3x
12y = -3x-4

make sense?

Answer 6

Yes

Answer 7

then you divide both sides by 12 to fully get y all by itself

12y = -3x-4
12y/12 = (-3x-4)/12
y = (-3x-4)/12
y = (-3x)/12 - 4/12
y = (-1/4)x - 1/3

Answer 8

y = (-1/4)x - 1/3 is in y = mx+b form

m = -1/4 is the slope
b = -1/3 is the y intercept

Answer 9

y = mx+b is slope intercept form

Answer 10

Thanks :D

Answer 11

you're welcome

Answer 12

So do the same to the other one?

Answer 13

IF they wanted it in slope intercept form, then yeah you would follow the same steps

Answer 14

but they don't want it in slope intercept form, they want it in standard form

Answer 15

Standard form is Ax + By = C

Example:
2x + 3y = 10

Answer 16

Oh Ok I think I got this part! Thanks so much!!

Answer 17

you're welcome

Answer 18

post what you get so I can check
