Pt Slope Formula
'Two Point Slope Form' is one of the methods of calculating the equation of a straight line. In the below two point slope form calculator, enter the X and Y coordinate values to find the straight line equation.
Positive slope $m0$, if a line $y=mx+b$ is increasing, i.e. If it goes up from left to right; Negative slope $m; 0$, if a line $y=mx+b$ is decreasing, i.e. If it goes down from left to right; Zero slope, $m=0$, if a line $y=mx+b$ is horizonal. In this case, the equation of the line is$y=b$; Undefined slope, if a line $y=mx+b$ is vertical. Start with the 'point-slope' formula (x 1 and y 1 are the coordinates of a point on the line): y − y 1 = m(x − x 1 ) We can choose any point on the line for x 1 and y 1, so let's just use point (2,3). Now, the slope intercept form also takes a point and a slope and give you the equation of a line. But, only if that point is the y-intercept. On the other hand, the point-slope form allows you to use any two points. Examples of the Point-Slope Form and Equation Example 01. Find the equation of a line through point ((1,3)) with slope (-1.

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
