In simplest terms and no jargon, here is how:
You have two points (x1,y1) and (x2,y2). Form a fraction and on top do x2 - x1 and on the bottom do y2 - y1. Reduce the fraction and you are done.
The two points you are either given or you need to use the equation to get them.
]]>may you tell me that
I just want to get the slop in any any point in the line any point I like and I want that not just from this table,
]]>In the days of yore we used to write it this way:
]]>please learn me how to do that.
]]>Your denominators are incorrect.
]]>so now it is between two points and it is 3.5 not 2,
can I know why that is happen? maybe I can find the slop of simple functions but I want to know further and further than that,
just tell me the reason please.
]]>That is a linear equation ( straight line ) the slope is constant.
May I see your calculations for the slope that do not end up with an answer of 2?
]]>before you see my question please look to that following picture :-
please if the slope is two inches per year, between 146 and 138 (Rise) and 8 - 4 (Run) and every two points between Run(8-4) from this Table. 1.2
I understand that and it is too clear... BUT!! my question is :- how to determine the slope in the same line between (146-133)= Rise! or in any value and versus Run(8-3)>Run...... these numbers I chose just for example cause that I mean is "why when I chose any value in the same line I don't get the same slope!!!! shouldn't be the same slope"2 pear year" ,, is there an error???
and the picture says : using any other two points on the line gives the same value.*
but I didn't get the same value when I chose any number why why why
