two point form of a line

Here you will learn two point form of a line equation with proof and examples. Let’s begin – Two Point Form of a Line The equation of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is  $y – y_1$ = ($y_2 – y_1\over x_2 – x_1$)($x_2 – x_1$) Proof :  Let m […]
