Please help! Slope intercept form
2x -3y = 12
What would this be in slope intercept form?

You're basically solving for y
OpenStudy (godlovesme):
@lizajune can u do that??
OpenStudy (anonymous):
no
OpenStudy (godlovesme):
Okay first step subtract 2x from both sides
OpenStudy (anonymous):
I got that far

2x-3y=12
2x-2x -3y = 12-2x
-3y = 12-2x
Do u know the last step??
OpenStudy (anonymous):
I ended up with y=15-2x Is that right?
OpenStudy (godlovesme):
Not quite u added 3 to 15 right?
OpenStudy (godlovesme):
I mean to 12?
OpenStudy (anonymous):
Yeah

-3 and y are multiplied so u have to do the opposite which is?
OpenStudy (anonymous):
Ok let me try again and see what I get
OpenStudy (godlovesme):
Kk (:
OpenStudy (anonymous):
y=4-2x?
OpenStudy (godlovesme):
Very close :D
But u have to divide 2 by 3 as well (u can leave it as 2/3)

So what would the slope of the line be?
OpenStudy (godlovesme):
Y=-2/3x+4
^^ is written in the slope-intercept form which is y=mx+b
M is slope
B is y-intercept
OpenStudy (anonymous):
Thanks a million!
OpenStudy (godlovesme):
Slope is -2/3
Y-intercept is 4

You're very Welcome!(:
