What is the y-intercept of the function f(x) = -x + } ?

Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{2}{9}[/tex] x + [tex]\frac{1}{3}[/tex] ← is in slope- intercept form
with y- intercept c = [tex]\frac{1}{3}[/tex]
