What is x - 3y = -9 in function form??? Help!

This is basically in the form y = mx+b with m = 1/3 as the slope and b = 3 as the y intercept. I'm using f(x) in place of y to indicate function notation.

Work Shown:

The goal is to solve for y.

x - 3y = -9

-3y = -9-x ... subtracting x from both sides

-3y = -x-9

y = (-x-9)/(-3) dividing both sides by -3

y = -x/(-3) - 9/(-3) ... break up the fraction

y = (1/3)x + 3 simplify

f(x) = (1/3)x + 3 replace y with f(x)

answer: sorry i can't you.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
