Answer:
y- intercept = [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 )
f(x) = - [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]
