Answer:
y=-7x-9
Step-by-step explanation:
y=mx+b(where m is slope and b is y intercept)
y=-7x+b
plugging the number in we get
12=-7(-3)+b
12=21+b
b=-9
so y= -7x-9

Hey there!
As you can see, they are lying on the same line.
When two angles are on the same straight line, they are adjacent. 
Adjacent angles are supplmentary. 
Adjacent angles= 180 degrees Supplementary= 180 degrees
They are choices "A" and "B". 
I hope this helps!
