$6.$Creat the scatter plot with $x$ axis is $hp$ and $Y$ axis is $mpg.(10)$

In $[6]$ :

$7.$Train the linear model using hp as variable and MPG as target and print ${}_0,{}_1(10)$

$($hint: use the fomula: $=(x^{T}x{)}^{-1}{x}^{T}y)$

In $[7]$:

$8.$Plat the scatter plot again with the line showing the linear model.$(10)$

In $[8]$ :

$9.$Random choose $3$ datapoint from the dataset, use the linear model to predict the MPG

with HP$,$ show the difference between predict value and real value. $(10)$

In $[9]$ :

$10.$Explain the why some differences are large, some are not$(10)$

In $[13]$

$11.$Find $R^2$ and use $R^2$ to explain whether the model is accurate.$(10)$
