How do I rewrite 2x+3y=1,200 in Slope intercept form?

Question

jdoe0001 · Answer

if you were to solve say " 2x+3y=1,200 "  for "y"   what would that give you?

thesmartone · Answer

Slope intercept form $\Huge\color{blue}{y=mx+b}$

anonymous · Answer

The equation for slope - intercept is y=mx+b. So y=2/3x+400 I believe.

anonymous · Answer

I don't really know what you mean jdoe0001

@fluteprincess352 Take the 2x on the other side and dived by 3 so that way y is all alone...

@typicalmatato You have to show and guide the person to the answer. Please take some time and read the Code of Conduct...

@fluteprincess352 What have you gotten yet?

anonymous · Answer

sorry guys stepped out for a sec had to do something

thesmartone · Answer

Sure no problem..

anonymous · Answer

so what do I do first?

thesmartone · Answer

subtract 2x

thesmartone · Answer

So what do you get now?

anonymous · Answer

do I subtract it from 3y or 1,200?

thesmartone · Answer

2x+3y=1,200
-2x        -2x
-------------
3y=-2x+1200

anonymous · Answer

I see thank you so much!

thesmartone · Answer

Now all you have to do is divide by 3 on both sides

anonymous · Answer

oh so once I divide both sides by 3 I get 3y=-2x+400

anonymous · Answer

??

thesmartone · Answer

No

thesmartone · Answer

3y=-2x+1200
--   ---   ----
3       3      3
=y=-2/3x+400

thesmartone · Answer

You have to divide everything by 3.

anonymous · Answer

oh ok I get it now thank you! :)

thesmartone · Answer

And now your equation is in the format of y=mx+b
and remember m is the slope and b is the y-intercept.

anonymous · Answer

yes I will remember this thank you!

thesmartone · Answer

No problem and $\Huge\color{purple}{Have~A~Great~Day!}$

you to! :)
