## Point Slope Form Calculator

Hi friends today we are going to discuss a very important topic in mathematics that is Point Slope Form Calculator, if we talk about co-ordinate geometry then point slope form plays a very important role in finding the equation of line, whenever we deal with geometry and we are asked to find the equation of line then always we need  two points from which the line is passing and also we need the slope of the given line so for making Point Slope Form Calculator we need two points and value of slope. As we well know that we have two axis’s one is x in horizontal direction and other is y in vertical direction, now suppose if we have two point as x1 and y1 and slope as m and we are asked to find the equation of line then the equation of line will be represented as,

x – x1 = m (y – y1),

If the value of x1 is 1 and value of y1 is 2 and value of slope m is 2 then the equation of line will be,

x – 1 = 2 (y -2),

x – 2y = -3.  (know more about Point Slope, here)

This is the required equation of line, we can also find the slope of line if we know that from which two point the line is passing, suppose a line is passing through points (x1 ,y1) and (x2 ,y2) then the slope of the line will be,

m = y2 –y1 / x2 –x1,

If we have one point as (1,0) and other as (2 ,1) then the slope of the line will be,

m = (1 – 0) / (2 -1),

m = 1.

So, the value of slope will be one, we can also write the equation of line as,

x – x1 = (y2 –y1 / x2 –x1) (y –y1),
