how do I right 2x + 3y = 1200 in function notation, what does the graph of the function represent ?

Question

campbell_st · Answer

well just make y the subject...

anonymous · Answer

then the answer for y would be 400

campbell_st · Answer

well almost... 

start by subtracting 2x from both sides of the equation 

3y = -2x + 1200

divide both sides by 3

y = -2/3x + 400

anonymous · Answer

how did you get that.??? two people have told me that now and I still don't get it

campbell_st · Answer

well subtracting 2x from both sides of the equation, moves it from the left hand side  to the right hand side of the equation. 

Then divide every term by 3 to get the value of a single y

ok so the function notation is what.?

anonymous · Answer

the value of y?

campbell_st · Answer

well that is just replacing y with f(x)
