# Point Slope Form Calculator + Online Solver With Free Steps

The online **Point Slope Form Calculator** is a calculator that allows you to represent a straight line in a **linear equation** form.

The **Point Slope Form Calculator** is a powerful tool that helps mathematicians and scientists to find the point-slope form of a line.

## What Is a Point Slope Form Calculator?

**A Point Slope Form Calculator is an online tool that helps you determine the point-slope form of a calculator of a straight line.**

The **Point** **Slope Form Calculator** requires two inputs: the value of the slope and the points the line passes. Using the inputs, the **Point Slope Form Calculator** quickly calculates the point slope from the line.

## How To Use a Point Slope Form Calculator?

To use the **Point Slope Form Calculator**, you will need to input the data of the line in their respective boxes and click the “Submit” button. The calculator will display the results in a new window.

The detailed instructions for using a **Point Slope Form Calculator** are given below:

### Step 1

First, we add the **value of the slope** into the **Point Slope Form Calculator**.

### Step 2

After adding the value of the slope, we add the **points where the line passes through** in the **Point Slope Calculator**.

### Step 3

Once we have entered both these inputs, we click the **“Submit”** button present on the **Point Slope Form Calculato**r. The calculator displays the point-slope form and a graph in a separate window.

## How Does a Point Slope Form Calculator Work?

The **Point Slope Form Calculator** works by taking in the inputs and turning the line equation into the point-slope form. The point-slope form is generally represented as the following equation:

**y – y1 = m ( x – x1 )**

## What Are Linear Equations?

A **linear equation** is an equation in which the variable’s maximum power is consistently 1; another name for this is a one-degree equation. A linear equation with one variable has the following standard form:

**Ax + B = C **

A is a coefficient, B is constant, and x is a variable in this situation. A **linear equation** is also known as a **linear equation** because it always produces a straight line when all possible solutions are graphed.

It makes no difference if you use whole integers, fractions, decimals, etc., for the x and y values. Each answer pair is on the graphed line. Nearly every part of life can benefit from using **linear equations**.

Examples include computing distance, calculating hourly pay, figuring out how much to charge in banking and engineering, and calculating how much medication to administer to a patient based on their weight and age.

A linear equation for a graph is usually represented by:

**y = mx + c **

## Point Slope Form

The **point-slope form** calculates the equation of a straight line inclined to the x-axis at a certain angle and passes through a particular point. The equation of a line is an equation that is satisfied by every point on the line. This indicates that a **linear equation **with two variables represents a line.

Multiple methods are used to find the equation of a line depending on the information given. When we know the slope of a line and a point on it, we may utilize the **point-slope** formula.

The **point-slope form** expresses a straight line by using its slope and a point on the line. The equation of a line with slope m and passing through a point (x1, y1) is determined using the** point-slope form**.

### Formula for Point Slope Form

The **point-slope form** **formula** is used to calculate the equation of a line. The point-slope form is used to calculate the equation of a line with a specified slope and a given point.

This formula is only utilized when the slope of the line and a point on the line are known. Other formulas for determining the equation of a line include slope-intercept form, intercept form, and so on. The **point-slope formula** is as follows:

**y – y1 = m ( x – x1 ) **

Where:

**Random point on line = (x,y) **

**Fixed point on the line = (x1, y1) **

**m = Slope of the line **

### Deriving the Point Slope Form Formula

The **point-slope formula** is derived using the equation for the slope of the line. Consider a line with slope m. Assume that (x1, y1) is a known point on the line. Let (x, y) be any other random point on the line with unknown coordinates.

We know that the equation for a line’s slope is:

\[ m = \frac{(y-y_{1})}{(x-x_{1})}\]

We multiply (x- x1) on both sides and get:

**m(x – x1) = (y – y1) **

Which can be written as:

**y – y1 = m ( x – x1 ) **

Hence this **derivation** proves the formula.
