use pandas python & numpy

I want number 2)

Extracted text: We all know that when the temperature of a metal increases, it begins to expand. So, we experimented with exposing a metal rod to different temperatures and recorded its length as follows: Temp Length 20 25 30 35 40 45 50 55 60 65 0.5 1.8 6.2 6.5 7.8 9.4 9.8 10.9 Required: 1. Implement and plot a simple linear regression for the above data, where the temperature is “x", and the length is "y" 2. Implement and plot a multiple linear regression "Polynomial regression" with different degrees. For example, Degree of 3: Y = Wix' + w2x²+ w3x³ + w4 Where w4 represents bias. *you can use normal equation to calculate 'W' as follow: W = (XT.X)-1.(XT.Y) Then calculate Y, Where Y = X.WT 3. Try degree of 2, 3, 5, and 8
