I mentioned the two basic forms, but there are many more. Essentially, if any value is 0, that part can be left out of the equation. The standard formula for one-variable linear equations is: \underbrace \\Īs we saw in the previous examples, they can gain different forms in certain situations. Graphing calculators are greatfor solving line equations and giving you graphs. They are a part of linear algebra, which is a very important branch, not just in mathematics, but other sciences, such as engineering, computing, and many more. And alwayskeep yourgraphing calculator handy on these typesof problems. Sir William Rowan Hamilton invented the linear equation in 1843. The variables are the unknowns of an equation, the missing parts if you will. The coefficients stand with the variables, and they serve to amplify them. This means that in any version of a certain equation, they always remain the same.

This free online slope calculator helps you find the slope and equation of the straight line. They are called that because they don’t change. A slope, also known as gradient describes the steepness of a line. The given numbers that stand alone are called the constants.

However, this doesn’t always have to be true (we will see some examples later).Įquations are made up of three parts. The right-hand side is generally assumed to be 0. We usually say an equation has two sides: the right-hand side, and the left-hand side. They can consist of any number of values and operations, with the only requirement being the expressions have to be equal. These two expressions are separated only by an equals sign (=). In mathematics, an equation is a statement that demonstrates the equality of two expressions. On the other hand, there is a lot of more interesting subjects on our site where you can learn what is Elastic Potential Energy for example, or check out Friction Force Calculator as well. Often we need to find the solution or the graph of a linear function, and with our calculator it has never been easier, just input two values and get your results.įind more math calculators, such as one for calculating the trapezoid perimeter, or maybe you want to do some Cross Product for vectors. This Linear Equation Calculator is a tool for finding a solution and graph of a linear function.
