What course are you in?  I'd guess Elementary Statistics.

If that's the case, I think you're looking for at least one of the following:
1) regression line for the given data (including slope and y-intercept)
2) correlation coefficient

Does any of this ring a bell for you?

its the qustion above that i posted

Exactly.  Just what kind of help do you need?  Exactly what are you looking for?  My initial response to your post was appropriate:  you probably need to find the regression line representing the function that relates the Temperature and the Velocity.  

If you're in Statistics, that's a fair question.
If you're just in Algebra, then find the slope of the line through the given points.  This will enable you to write the equation of a straight line in the form y=mx+b.
