question is down below thanks

Answer:
E
Step-by-step explanation:
A linear equation is in the form of: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
m is the slope and it's given, which is -6
b is the y-intercept and it's given, which is 9
When we plug in to the form we get:
[tex]y=-6x+9[/tex]
