Formula For Two Point Form
(y – y1) = (y2 – y1)/(x2 – x1){x – x1}
(y – y2) = (y2 – y1)/(x2 – x1){x – x2}
where,
- (x, y) is an arbitrary point on the line.
- (x1, y1) and (x2, y2) are coordinates of points lying on the line.
Two Point Form – Definition, Formula & Derivation
Two-point form of a line is the equation of a line when two points on a line are given, the two-point form formula is Y − y1 = (y2 − y1)/(x2 − x1)(X − x1). Where the two points are, (x1, y1) and (x2, y2). If in geometry two points are given then the equation of the line passing through these two points is given using the two-point form of the line.
In this article, we will learn about the two-point form, the equation of a line in the two-point form, Two Point Form examples, derivation of the two-point form, and others in detail.
