Question:
(a) Find the straight line that provides the least-squares fit to these data.
(b) Use the method from Section 1.2 to find the equation of the straight line passing through the two points.
(c) Explain why we could have predicted that the straight line in (b) would be the same as the straight line in (a).

During my undergraduate i used to participate as TA (Teaching Assistant) in several electronics and computers subject. I'm passionate about learning Computer Science as my bachelors are in Electronics but i learnt most of the Computer Science subjects on my own which Machine Learning also. At Present, i'm a working professional pursuing my career as a Machine Learning Engineer and i want to help others learn during my free hours, that's all the motivation behind giving tuition. To be frank i have no prior experience of tutoring but i have solved problems on opensource platforms like StackOverflow and github. ~Thanks
