Straight Lines _Quick notes

Just when you think "Hey, I went through the entire roller coaster of trigonometry, climbed the logarithms mountains and swam through the monstrous sea of quadratic and binomial theorem, something as simple as a straight line cannot get too complicated (I mean, it is just a straight line , not curved, not an ellipse , just a collection of dots , after all!) It can't be that important "

That's when our very dear mathematicians got too offended ,hence ,decided to include close to 50 formulas on that basic concept.

<Moral of the story :-

1) Do not offend the mathematicians, they have too much power of changing the school lives of thousands of generations

2)Treat all chapter with equal care and respect वरना बाद में पछताओगे >

This blog consists of the various rules, new terms (definitions) and , ofcourse, formulas from the chapter 'Straight Lines'

< To be honest, I didn't expect 7 pages worth of formulas from this chapter!, Well, I tried to include as many useful formulas as possible including few short cuts to make our life easier, Hope it's useful to y'all>
