What is a linear equation in one variable?

What is a linear equation in one variable?

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it.

What is the single graph method?

The single-graph method is a technique used in algebra where a function is plotted into a graph. This graph shows the nature of the function, concavity of the function as well as important points in the graph such as x- and y- intercepts. The graph of a function can also be used to find the solution of a function.

What is a linear equation on a graph?

A linear equation, sometimes called a linear function, is an equation that forms a straight line when graphed. The graph of the equation can be displayed on horizontal and vertical lines to give each x-coordinate and y-coordinate concrete values.

What are the uses of linear equations in one variable?

Linear equations in one variable can be used to calculate the value of an integer when we are given two or more integers with one of them being unknown. Using the expression in an equation form, we can easily find the value of an unknown integer.

How do you graph a linear graph?

How To: Given the equation for a linear function, graph the function using the y-intercept and slope.

1. Evaluate the function at an input value of zero to find the y-intercept.
2. Identify the slope.
3. Plot the point represented by the y-intercept.
4. Use riserun to determine at least two more points on the line.

How are linear equations represented in one variable?

Standard Form of Linear Equations in One Variable. The standard form of linear equations in one variable is represented as: ‘a’ and ‘b’ are real numbers. Both ‘a’ and ‘b’ are not equal to zero. Thus, the formula of linear equation in one variable is ax + b = 0.

Which is the graphical solution of a pair of linear equations?

Graphical Method of Solution of a Pair of Linear Equations: An equation in the form of \\(ax+b=0\\), where \\(a, b\\) are real numbers, and \\(a≠0\\) is called a linear equation in one variable. And every linear equation in one variable has a unique solution.

How to solve an equation with only one variable?

For solving an equation having only one variable, the following steps are followed Step 1: Using LCM, clear the fractions if any. Step 2: Simplify both sides of the equation. Step 3: Isolate the variable. Step 4: Verify your answer. Let us understand the concept with the help of an example.
