Note ! This is not a question .This is my new series of Tutorials,in this one I am taking up the topic "STRAIGHT LINES" because i see a major part of the questions asked in OS maths section is something like "write slope point form equation of this line", "write the equation of line passing through points.." etc.
So here we go .Do not forget to provide your valuable feedback.Feel free to link this tutorial to students when they ask these types of questions again. Happy openstudying !
P.S. Vedic mathematics tutorials will also be continued. Don't worry :)

Best ResponseYou've already chosen the best response.0I love this, its really great! I love the colors, lol. :o) Maybe you could add some examples of how to find and put equations and points into the formulas? I know when I'm learning, it always helps to look (and sorta follow) examples.

Best ResponseYou've already chosen the best response.0Agreed, examples would probably help some of the more... persistent minds. That is when you get the time, this is wonderful as is, just a bit of finetuning might help.
