Question

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

Answer 1

well just make y the subject...

Answer 2

then the answer for y would be 400

Answer 3

well almost...

start by subtracting 2x from both sides of the equation

3y = -2x + 1200

divide both sides by 3

y = -2/3x + 400

Answer 4

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

Answer 5

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

Answer 6

ok so the function notation is what.?

Answer 7

the value of y?

Answer 8

well that is just replacing y with f(x)

Answer 9

ok. thanks
