Mathportal is the last website in the list, as it provides a little more. It inputs points and outputs the line equation in general form and also in slope-intercept form.

It can also show you the steps of calculations and provide you with the closest exact answer from the equation. It also has a settings option to hide steps and to give you the most immediate solution.

It also draws the graph with the solution and has many solved problems to practice if you’re looking for some. It also guides their process of calculating the results. So, if you’re curious about their method, it’s there for you.

**6. Linear Equation Solver**

All the websites mentioned above have their own pros and cons, and it’s totally up to you to choose between them. You can put the hook right where you find the most comfortable and all you need. Every website is exact and up to the standard.

These websites not only give you the answer but also go a long way to teach you about the process.It is very much possible that you’re somewhere you don’t have a network for any reason. You want the calculator without the internet and always with you.

You can certainly have these apps on your phone for this purpose. This article will review some of the best ones for you so that you can choose the one according to your needs and comfort.

**Linear Equation Solver** is an elementary yet, powerful app for mathematical problems. You can have this app on your phone. It will benefit you in the line equation from two points problems and other linear problems.

So it can work like your go-to place for all linear issues. It is very accurate and easy to use. Cherrie on top is that it’s free.

**7. Mathway**

Mathway is also a handy, powerful, and diverse application for Ios and Android. It can solve complex math problems, including line equations from two points problems.

It is very accurate and helpful. It can help you with your linear equations and all the other mathematical problems. This app has a diversity of math calculators that even cover advanced calculus problems and complex equations.

It is also a free-to-use application.

**8. CameraMath**

CameraMath is also available on Ios and Android. It is an app that can solve line equations from two points but in a unique way. You can also use your phone’s camera and the app to solve the problem.

Where you need to input the variable and do a little hectic work on other apps, it allows you to snap a picture and have your solution right away. But to use this feature, an internet connection is necessary.

All these apps are efficient, and these outputs the results are in slope-intercept form. You can have these on your phone in case you don’t have access to the facility of internet. Just like the applications suggested above, it is also free to use application.

**Basic Concept**

The basic equation of a line is ‘ax+by+c=0’, and ‘a’ and ‘b’ are never zero, and c is the y-intercept. The slope-intercept form of the line equation is given by’ y=mx+c.’

The slope is the steepness of the line on the XY coordinate plane. These steps can calculate a line equation that passes from two points:

**Step 1**

- Find the slope using the slope formula:
**rise/run**,. - Find point 1 (x1,y1).
- Find point 2 (x2,y2).

**Step 2**

- Suppose you have the value of the slope, use one point to find the value of y-intercept(b). X or Y replace the ‘x’ in the equation of y=mx+b.
- ‘m’ becomes the slope calculated.
- Now the only variable left is ‘b.’

**Step 3**

Once you have the value of ‘m’ and ‘b,’ you can calculate the value of the line of the equation between two points.

If it is a horizontal line, the value of the slope is **zero**, and the intercept is equal to the y-coordinates as it runs parallel to the x-axis. The line equation, in this case, becomes **y=y_1**

If the line is vertical, the intercept’s slope and value go in an **undefined** condition. It becomes impractical to solve the equation. The line equation, in this case, becomes **x=x_1**

**End Note**

All these calculators and websites would fulfill your needs about line equations from two points. You can choose any of these as per your own needs.

If you want a more detailed calculator, it’s listed here and with the most simplistic calculator. Websites that not only solve problems but also teach you the method of solving the problems manually along the way.

It has also listed some applications that you can download for this use. These applications solve line equations from two points tasks and other complex equations. These have unique features.
