Can anyone please tell about slope function

I am not surprised.  I work in the US and I also handle a lot of graduate students in the biological sciences as well as in the field of business administration. About 85% of these students have no understanding about linear regression or about slope or even if they know it, they have no understanding about what it implies.  Microsoft Excel has taken the understanding out of statistics.  I don't expect them to know it either, since they learn it as they go.  I am sure all of them would learn a lot of regression analysis in colleges, but just like most of us, we tend to shed information that we don't usually use.  So the criticism of this student is uncalled for. 
  I appreciate Sudheer in taking a pro-active approach in trying to understand slope and its implications in the equation.  I would also say the comments from Wo about being politically correct is the main problem we face in students today.  A lack of scientific rigour in learning the right way of doing things, but just trying to trick the system into getting marks.  A person who tells me that it is perfectly OK to put a dependent variable on the horizontal axis, since he thinks that it is easier to trick the system should be the focus of criticism rather than a person who is trying to understand something he has not learned before.

I know I will be called a bad, bad person but it really bugs me 
and I think it's a fair question: 

How did we ever get to the point that a person who does not 
understand linear equation can:

1. Graduate from high school?
2. Be accepted to college? 
3. Be allowed to do scientific work in the lab?
