Question

can someone help me learn how to do slope-intercept form? please?

Answer 1

\[y=mx+b\] is slope intercept form, because \(m\) is the slope and \((0,b)\) is the \(y\) intercept

Answer 2

I get that. But, how do i change The equation 2x + 3y = 1,200 into slope intercept form?

Answer 3

i've been stuck on this for a week i'm not good at algebra sorry..

Answer 4

first subtract 2x from each side

Answer 5

2x+3y=1,200
-2x -2x
---------------
x+3y=1,198x?

this is where im confused how do i subtract 2x from 1,200?

Answer 6

first
for the left hand side
2x+3y_2x =??

Answer 7

is that 2x+3y-2x?

Answer 8

2x+3y-2x=3y

Answer 9

the right hand side will be
1200-2x

Answer 10

Okay so the 2x's cancel each other out?

Answer 11

yes right

Answer 12

okay now what do we do??

Answer 13

the equation will be
3y=1200-2x
by comparing with
y=mx+c
the coefficient of y must be 1
how ??

Answer 14

i dont understand im sorry.. :(

Answer 15

y=mx+c
3y=-2x+1200
you have to divide your equation by 3 to get the standard form

Answer 16

\[\frac{ 3y }{ 3 }=\frac{ -2x }{ 3 }+\frac{ 1200 }{ 3 }\]

Answer 17

\[y=\frac{ -2 }{ 3 }x+400\]
where
slope =-2/3
y-intercept=400
