Question

2x+y=5

Answer 1

Make y a function of x
To make y as a function of x means to make y depend on x.
To do so, isolate y. The goal is to place y alone on one side of the equation.
2x + y = 5
Subtract 2x from both sides. y = -2x + 5....This is your answer.
In the equation, y = -2x + 5, the value of y depends on the value(s) you select for x.
This is why it's called "y as a function of x."
Since, y = f(x), we can also write your answer this way:
f(x) = -2x + 5
