Answer:
Modeling the relationship between a scalar variable y and one or more variables denoted X. In linear regression, models of the unknown parameters are estimated from the data using linear functions.
polyfit( x,y2,1) %return 2.1667 -1.3333, i.e 2.1667x-1.3333
polyfit( x,y2,1) %return 2.1667 -1.3333, i.e 2.1667x-1.3333
