Choices:
(A) $y=b x+c$
(B) $y=c x+b$
(C) $y=a x+b$
(D) $y=a x+c$
(E) $y=c x+a$ You FIRST think about the reasoning process as an internal monologue and then provide the final answer. The reasoning process MUST BE enclosed within <think> </think> tags. Please answer the final answer within the <answer> </answer> tags.
