How to find slope for points not given

Not sure if that made sense, but for this question I was given the following data points to graph

Code:
          Time                 Distance
            2                       5
           2.9                     10
           3.9                     20
           4.7                     30

And I'm supposed to find the slope at 2s, 3s,4s, and 5s. But I don't really get how. I don't need to know the answer just how to figure it out! Please and thank you.

Have you covered linear regression yet? You'll find the needed formulas around the middle of the page. If you've got access to MS Excel, there is a package in there that will do the work for you. If you haven't covered linear regression, then I'd graph the data, sketch in a best fit line, and calculate the slope of that.
