Writing a linear equation An algebraic equation in which each element or term is either a constant or the product of the first power of a single variable and a constant is called a linear equation.

These equations can have one or more variables.

The slope tells how much the value of one variable changes if the other one changes by a single unit. If you are calculating the value of y, the intercept shows at which point the line crosses the y-axis.

How to write a linear equation There are several different forms of linear equations that can be converted from one to another using the basic laws of elementary algebra. We will explain the ones that are most often used in practical mathematics.

The general form Depending on the number of variables if we represent the variables with x1, x2, x3…, xn and the constants with a1, a2, a3… an and bthe general form of a linear equation looks like this: It generally looks like this: It can be converted to the general form, but not always to other forms of equations if the value of a or b is equal to zero.

The slope-intercept form This is also a very commonly used form of linear equations. It is called the slope-intercept form because both slope and the intercept of a line can be simply read from equations expressed in this form.

It looks like this: The important thing to remember is that equations of vertical lines cannot be expressed in this form, as their slope is undefined. These are the basic forms of linear equations. Now, to write down a linear equation in one of these forms, keep a few things in mind.

First, it helps if you have a visual representation of the linear equation you are trying to write down. So, if you are given two or more points through which your line passes, draw a graph first.

Secondly, try finding the intercepts and the slope. They are generally easy to find and it is easy to convert a slope-intercept equation into most other forms.

It might seem a bit complicated now, but with some practice it will become all too easy. To practice the skill of writing a linear equation, please use the math worksheets below. Writing a linear equation exams for teachers Exam Name.Graphing Lines in Slope-Intercept Form Worksheets.
