Hey there, ryo! Do you understand this topic at all or are you completely lost?

@ryo

anonymous · Answer

uh...kinda understand it i guess but sorta lost ^^;;

anonymous · Answer

something to do with Ax + By = C or something right?

anonymous · Answer

Oh, that's perfectly fine! I can break it down for you. Do you understand how to find the slope of a line?

And yes, you are on to something! :)

anonymous · Answer

i dont remember how to do the slope >.<

anonymous · Answer

Hey there... this form is known as **two-point form** (as it is based on equation of a line passing through two points :-) )

Slope is given by...

|dw:1365630170451:dw|
(since plotting these two points on the coordinate system will give you it's inclination , tans equal to this value...) 
Here 's' is the angle the line would be making with positive direction of 'x' axis...

Hope this helps :-)
