Could someone please help me with this. The problem says that the table gives the price (p) in cents of a first class stamp over time where t is the number of years since 1970. I am to find the line of best fit for the data.

Code:
t  1   4   5   8  11  11   15  18  21  25  29
p  8  10  13  15  18  20   22  25  29  32  33
Thanks!
