# Linear Function

The linear functioncan be interpreted as a form of function consisting of variables that are one or two in numbers. The linear functions include the variables that do not contain any exponents. A linear function constructs a completely straight line.

## Understand the Slope of the Linear Function

The slope of the linear function is known to be consistent. When the straight line of a linear function is drawn vertical then that is considered to have the undefined slope. When the straight line of a linear function is drawn horizontal then that is considered to have zero slopes.

## Examples of the Linear Function

Examples are considered to be one of the best ways to clear the concepts of a certain topic. A few examples of linear functions are:

•  f(x) = 100
• x/188 + y/200 = 1
• x/100 + y/140 = 1
• x/88 + y/90 = 1
• f(x) = 66x + 33y
• f(x) = 56x + 74y
• x/67 + y/89 = 1
• x/197 + y/298 =1
• f(x) = 367x + 467y
• f(x) = 789x

## Standard Structure of the Linear Function

The standard structure of any linear function is:

AX + BY = C

## Non-Linear Function

The non-linear function can be interpreted as the form of a function that does not construct a completely straight line. In very straightforward words, the non-linear function can be interpreted as a function that is not contemplated as a linear function.

## Examples of Non-Linear Function

A few of the examples of the nonlinear function are specified below:

•  Any parabolic functions are contemplated as the non-linear function.
• Any quadratic functions are contemplated as nonlinear functions.
• Any inverse functions are contemplated as the nonlinear function.
• Any exponential functions are contemplated as the nonlinear function.

## How to Solve the Graphs of Linear Functions?

There are a series of steps that are needed to be followed to solve the graphs of the linear functions. Those steps are illustrated below;

•  For the very initial step, one has to get the two levels. These two levels should fulfill the equation.
• Then on the successive step, one has to form those got levels on the plane of XY.
• In the following step, those two levels are supposed to be joined.
• Those two levels are supposed to be joined with the assistance of a straight line.
• Accordingly, the graph will be formed for the given linear function.
