Linear Regression for Dummies

In my previous article, I have highlighted 4 algorithms to start off in Machine Learning: Linear Regression, Logistic Regression, Decision Trees and Random Forest. Now, I am creating a series of the same. The equation which defines the simplest form of the regression equation with one dependent and one independent variable: y mx c. Where y estimated dependent variable, c constant, m regression coefficient and x independent variable. Let's just understand with an example: Say; There is a certain relationship between the marks scored by the students (y- Dependent variable) in an exam and hours they studied for the exam(x- Independent Variable).
