Help I literally don’t know

Answer:
C
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 )
Given
y + 6 = [tex]\frac{1}{3}[/tex](x - 9) ← distribute
y + 6 = [tex]\frac{1}{3}[/tex] x - 3 ( subtract 6 from both sides )
y = [tex]\frac{1}{3}[/tex] x - 9 ← in slope- intercept form
