# Using the Point-Slope Form of a Line The point-slope form is said to be one of the three forms that are used to represent the straight line. This form is beneficial, and the reason for it is that it helps us to calculate the equation of a line by using a point of a line and the slope of that line. The rest of its forms are known as standard form and slope-intercept form. But the most commonly used form is the slope point form. The process is difficult for a few people, so we recommend using the point slope calculator that calculates the equation of a line according to the coordinate points and slope of the line.

## How to Write Point-Slope Form?

By using the formula of point-slope, we can express the equation for a line as:

y – y_{1} = m(x – x_{1})yy1​=m(xx1​)

You might have an understanding of the x & y variables of the equation, but what is meant by x_{1}, y_{1}x1​,y1​, and m? so know about the other variables of the equation swipe up the page.

## What is x_{1}x1​ and y_{1}y1​?

The x_{1}x1​ and y_{1}y1 terms are the numbers that represents the x-coordinate & y coordinate of the point of a line. Suppose a graph in your mind has points (1, 0) on the line. Here 1 represents the x-coordinate of the line, and 0 represents the y-coordinate of the line. So you can say that x1 is equal to 1 and y1 is equal to zero.

However, the points (0, -1) are also a part of the line. Here the question that will bother us is that does it mean we are using the wrong point? The answer for it is simple “no”. In other words, you can say that x1 = zero while y1 is equal to -1. You feel that this process is complicated then, consider using the point slope calculator for the slope and equation calculations.

Generically, we can use x_{1}x1​ and y_{1}y1 for the representation of x- & y- coordinates of any unknown point of the line. Here the tip is not to confuse x_{1}x1​ and y_{1}y1 with x and y variables. You need here to understand that x & y variables represent any of the points of the line. We know this is so confusing, so we want you to try the point slope form calculator that displays its solution with the graph.

## How to how to find point slope form of a Line?

The letter m of the point-slope form equation is known as a number, which represents the slope of the line. A few of the people take the slope of the line as it rises over-run. If the two points of the line are identified, you can determine the slope of the two points with the assistance of the slope formula. If the two points of the straight line are known, then you can calculate the slope of the line by using the point slope calculator or by the below-mentioned formula.

m=run / rise​=x2​−x1 / ​y2​−y1​​

The same idea will work great here and if we use two points of the line. Then we can determine the slope of the line by utilizing the formula mentioned above. Instead of using the slope formula, a considerable option is to use the point slope calculator that finds the straight-line equation by utilizing the coordinates and slope. The best thing about using this point slope equation calculator is that you can do the calculation without spending money.
