The video tutorial explains how to create and train a linear regression model using the Sklearn library. It covers the process of fitting the model with data, making predictions, and understanding the coefficients and intercepts. The tutorial also demonstrates how to manually calculate the price of a house using the model's coefficients. Finally, it introduces the concept of multiple linear regression as the next topic.

What is the first step in creating a linear regression model using Scikit-learn?

• Running the prediction cell

• Calculating the coefficients

• Predicting the price of a house

• Importing the linear model from Scikit-learn

Which method is used to train the linear regression model with data?

• Reg.predict()

• Reg.fit()

• Reg.train()

• Reg.calculate()

How do you predict the price of a house with a given area using the model?

• By using Reg.train() with the area

• By using Reg.calculate() with the area

• By using Reg.predict() with the area

• By using Reg.fit() with the area

What does the Reg.coef_ method return in a linear regression model?

• The intercept value

• The coefficient value

• The predicted price

• The area of the house

How can you manually calculate the predicted price using the model's coefficients?

• By multiplying the area with the intercept

• By adding the coefficient to the area

• By multiplying the coefficient with the area and adding the intercept

• By dividing the area by the coefficient
