Step 1

The linear regression equation always passes through (x, y)

y =a + bx

Let there be two variables: x & y.

y – Regression or dependent variable or explained variable
x – Independent variable or predictor or explanatory variable

Step 2

On minimizing the least squares equation, here is what we ...
