Python for Machine Learning - The Complete Beginners Course - Line Representation

The video tutorial explains the linear equation Y = mX + b, where Y is the dependent variable and X is the independent variable. It describes the slope (m) and Y-intercept (b) and applies this equation to real estate, using surface area as the independent variable to predict house prices. The tutorial also covers finding the best fit values for m and b to make accurate predictions.

In the equation Y = mX + b, what does the variable 'm' represent?

• The slope of the line

• The dependent variable

• The Y-intercept

• The independent variable

In the context of the equation Y = mX + b, if X is the surface area, what is Y?

• The price

• The slope of the line

• The Y-intercept

• The surface area

Why is surface area considered the independent variable in the equation relating area and price?

• Because it determines the slope

• Because it is used to calculate the price

• Because it is the Y-intercept

• Because it is dependent on price

What is the purpose of finding the best-fit values for m and b in the equation Y = mX + b?

• To find the slope of the line

• To determine the independent variable

• To calculate the Y-intercept

• To accurately predict Y for a given X

How can the price of a house be predicted using the equation Y = mX + b?

• By using the surface area as X and calculating Y

• By using the price as X and calculating Y

• By using the slope as X and calculating Y

• By using the Y-intercept as X and calculating Y
