I'd go with D, although I'm not sure... The pattern works with D's equation..It is precise but not completely accurate (y values are off a little)

Should the options C and D be written:
y = -3/10x - 35
y = - 3/10x + 35

@melstutes I based my answer on C and D being as @kropot72 said. Are they supposed to be like that?
