Your questions are too general...we can't teach here.
Are you a student attending math classes?

If someone asked you "how do you make a car?", you'd reply "do you know what steel is?", right?
 
I guess that means: Texas Tech University , Distance Learning Program

Regardless, we're here to answer specific questions, not teach full topics :shock:
 
If you will give us a set of data, we can help you find the equation of the regression line.
