2Models are called linear when they are a linear function of the coefficients. – Michael R. Chernick Nov 01 '19 at 03:40

2Ok i got the answer. For the model to be linear it needs to be linear in terms of parameters not the predictors. Here betas are parameters and horsepower is predictor – Bhuwan Bhatt Nov 01 '19 at 03:55

I'm voting to close this question topic because the OP answered it in a comment – Peter Flom Nov 01 '19 at 11:39

In order to explain this, I would consider the following quadratic function.
By comparing this function with your function, x1 would be similar to your hp (horsepower).
Actually what we have really done is, we have created a new feature x2 where
By plugging this new feature to the above hypothesis we get the following function which is just like a linear model
