9 Best Free Linear Equation Grapher Software For Windows

This article lists Best Free Linear Equation Grapher Software For Windows. All of these software are beneficial for students for plotting graphs of linear equations. Most of these let you plot only 1 variable linear equations, while some can plot linear equations with 2 and/or 3 variables too. Besides linear equations, you can plot the graph of other equations too. Such equations include quadratic equations, cubic equations, trigonometric equations, etc.

In most of these software, you can input more than one equation. In such a case, the graphs of all the equations are plotted on the same plane. You can define different color schemes for each of the plotted graphs for easy recognition.

While some of these software require only numerical values, some require a complete equation to plot a graph. You have to enter an equation in the same manner as you write it in your notebook. Talking about the general features, the features such as move, zoom, select, etc. are also available.

Some of these software can plot both 2D and 3D graphs of the entered equations. You can save both the view of graphs in JPG, PNG, BMP, etc. image formats.

I have also added a command line based tool to plot the graph of linear and other equations. Despite being a command line tool, it is easy to use. You just have to enter an equation and it plots respective graph.

In some of these software, you will also find the measurement tools. Using these tools, you can calculate the area of a region, length of a line segment, an angle between two line segments, etc.

GraphCalc is limited to plot a graph of linear equations with one variable.

Two Equations - Two Unknowns

Two Equations – Two Unknowns, as the name implies, is a linear equation grapher which can plot a graph of up to two linear equations simultaneously. Also, the linear equation supported by it is linear equation with two variables. In order to plot a graph, you have to enter the values of coefficients and constant terms in their respective boxes. After that, press Solve button. It plots both the linear equations on the same graph with two different colors, blue and red.

Apart from plotting a graph, it also shows the solution of the entered problem. The method used by this software to solve the system of linear equations is Cramer’s Rule.

Equation analyzer

Equation analyzer is another free Windows 10 app to plot a graph of both linear and quadratic equations. It is a basic grapher software which is limited to plot a graph of only one linear equation at a time.

A linear equation in the form AX + C = BY (linear equation with two variables) is displayed on the interface. Here, A and B are the coefficients of the variables X and Y respectively and C is the constant term. You have to enter the values of these terms and click on Calculate button. After that, it calculates the root of that equation and plots its graph. In addition to this, it also displays the properties of the linear equation, like minimum or maximum point, monotonicity, even or odd function, continuous function, etc.

Limitations of this free linear equation grapher software:

• Graph of only one equation can be plotted at a time.
• It does not show scales on both X and Y axes, which makes the graph difficult to read.

WeissCalc

WeissCalc is a simple linear equation grapher software for Windows. This free software can plot graphs of up to 3 linear equations at a time. You just have to enter the required data and click on Graph It! button. Besides linear equations, it also plots a graph of quadratic equations. The value for quadratic equations’ graphs is also limited to 3.

You can also select the particular equations out of the entered ones to plot graphs.

Other calculators include: basic calculator, quadratic equation root finder, prime number detector, and simple trigonometry solver.

Limitations of WeissCalc:

• The value of the coefficient of variable Y cannot be entered.
• The graphs of all the entered equations are represented with the same color, which makes it difficult to differentiate.
• The plotted graph has no scale on abscissa and ordinate. This makes the graph difficult to analyze.

Even though the format of linear equation displayed by this software is of linear equation with two variables type, but you can edit the coefficient of one variable only.

Console Grapher

Console Grapher is a command line based application to plot graphs of different equations including linear equations, quadratic equations, cubic equations, trigonometrical equations, etc.

Though it is a command line based software, it is very easy to operate. You just have to enter an equation and press enter button. It then plots the graph of the entered equation. The plotted graph is in the form of dotted lines.

Limitations of Console Grapher:

• It does not plot more than one graph on a single plane.
• There are no markings on both the axes.

Console Grapher is a portable linear equation grapher software.

NOTE: ConsoleGrapher supports the linear equation with one variable only.
