Default *ANSWER* Question 4 linear regression hypothesis

On question 4, I tried to fit each of two sample points through (i) h = ax, and (ii) h = ax+b. I found that hypothesis (i) gave me an average of "a" quite different to any of the answers, but hypothesis (ii) gave me an average of "a" very close to one of the answer options and the average of b is virtually close to 0. If average of b is 0 in (ii), why the average of a are different in (i) and (ii)? Can anyone help me explaining these?
