how do i know what slope a line is very easily

Ok phil thanks so much and just to clarify you CAN do the ordered pairs in any order so if I had the pairs (9,6) and (4,3) then I could do 

6-3=3

--------

9-4=5

and get a slope of 3

                              -

                              5

and it doesn't matter which of  the ordered pairs go first.

Thanks so much guys!

can you be more clear, the question is a bit vague

Sorry just made my acct.

Does anyone know how to find the slope of a line in a quick and easy to understand way?

I am not ever able to get the slope of a line in a short amount of time which makes my HW for school take forever.

I want a way that I can understand not the stuff that they teach us in Schools.

Do you know how to derive? its how you find the tangent(slope) of complex functions. If no, you can find 2 points on the line and divde (y2-y1)/(x2-x1)

I myself use derivatives, its simple, fast and useful, which you will figue later in your school year or lifetime.

ok so it is (x1-x2) but how do i tell which ordered pair is first. Or does it even matter?

If you're given two points....here's an easy way  [ no "formulas"  involved ]

Example  ......find the slope of a line containing the points  (3, 5)  ( 6 , 20)

1st ...  subtract the y coordinates in any order.....I'll do  (20 - 5)  = 15

2nd ....subtract the x coordinates in the SAME  order  (6 - 3)  = 3

Put the first thing OVER  the second

15 / 3   =  5       and that's the slope  !!!!

Pretty easy, huh???

Yep.....as long as you keep the order the same.....you will get the same result....
