Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form. Two Point form is one such method used to find the equation of a straight line when there is no slope and the straight line is in a Cartesian plane passing through two given points.

This online Two Point Slope Form Calculator helps you to find the equation of the straight line using the Two Point Form Method. Enter the values for X and Y co-ordinates for two points. This analytical method is used since it is a plane and not a slope, just the two sets of X and Y coordinates (x1 , y1) and (x2 , y2) are enough to calculate the equation of the straight line.

Example

Two Point Slope Form

Let us consider the co-ordinate points (x1,y1) and (x2,y2) as (9,1) and (8,2), then
(Y - 1) / (2 - 1) = (X - 9) / (8 - 9)
(Y - 1) / 1 = (X - 9) / -1
- (Y - 1) = (X - 9)
(-Y + 1) = (X - 9)
X + Y - 10 = 0
