Question 93317: i have a math packet and i only have 2 questions left. The directions say EXACTLY this:
"Write the equation in function form"
and the question is this:
-4x + 6y = 24
I've checked a lot of help sites and asked a ton of people but i still can't find the answer. Can you tell me how to solve the problem?

Write, in function form:
-4x%2B6y+=+24
First, you need to identify which of the two variables is the "independent" variable. Usually, x is the independent variable, so we'll first write the equation in terms of x, which means that we'll need to solve for y.
-4x%2B6y+=+24 Add 4x to both sides.
6y+=+4x%2B24 Divide both sides by 6.
y+=+%282%2F3%29x%2B4 Now, to write this in function form, we replace the y with f(x), which is read as f of x or function of x. The nice thing about an equation written in function form is that it easy to identify the independent variable. That's the variable inside the parentheses of the f(x).
f%28x%29+=+%282%2F3%29x%2B4
