Answer:
D alternate exterior angle
Step-by-step explanation:
It is D because you would do x+6 and would get y so it represents direct proportion
A vertical translation 1 unit down since for example x is 1, if u plug it in both equations it is f(1)=1*2-1 which equals f(1)=1 and the point is (1,1) for the other one, g(1)=(1-1)2-1 it equals g(1)=-1
