You can determine if a function is linear by examining its graph or its equation. A linear function will produce a straight line when graphed, and its equation can be expressed in the form (y = mx + b), where (m) and (b) are constants. In contrast, a nonlinear function will create a curve or other shapes on the graph, and its equation may involve exponents, products of variables, or other non-linear terms.
A linear function would be represented by a straight line graph, so if it's not a straight line, it's nonlinear
To be linear, there should only be constants, and variables with constant coefficients. No powers of variables, or numbers raised to the power of a variable, or any other nonlinear function such as log, ln, sin, cos, tan, cosh, etc.
An equation is linear if it can be expressed in the form (y = mx + b), where (m) and (b) are constants, and the variables are raised only to the first power and multiplied by constants. In contrast, an equation is nonlinear if it includes variables raised to powers greater than one, products of variables, or functions such as exponentials, logarithms, or trigonometric functions. To determine the linearity, check for these characteristics in the equation. If any of these nonlinear elements are present, the equation is nonlinear.
If it can be written in the form y = mx + c where m and c are constants [or, equivalently, ax + by = k where a, b and k are constants] then y is a linear function of x.
To determine if a table represents a linear function, check if the differences between consecutive y-values are constant when the x-values increase by a consistent amount. If the change in y is the same for every equal change in x, the function is linear. Additionally, the graph of the function would form a straight line. If either condition is not met, then it does not represent a linear function.

A function is linear if one variable is directly proportional to the other.
An equation is linear if it can be expressed in the form (y = mx + b), where (m) and (b) are constants, and the variables are raised only to the first power and multiplied by constants.

By looking st two linear equations you can tell that the corresponding lines are parallel when the slope is the same. The slope controls where the line is.
If it can be written in the form y = mx + c where m and c are constants [or, equivalently, ax + by = k where a, b and k are constants] then y is a linear function of x.
A linear function, of a variable x, is of the form ax+b where a and b are constants. A non-linear function will have x appearing in some other form: raised to a power other than 1, or in a trigonometric, or exponential or other form.

The word linear means in a straight line. If the graph is a line, it is linear. Also, linear equations are of the first order; they contain a variable but not a square (or higher power) of a variable. If the equation contains x2 it is not linear.
The precision of a linear approximation is dependent on the concavity of the function. If the function is concave down then the linear approximation will lay above the curve, so it will be an over-approximation ("too large"). If the function is concave up then the linear approximation will lay below the curve, so it will be an under-approximation ("too small").
An equation is a statement that two things are equal. A function is a rule or process that gives you a value if you give it something in its domain (the set of things on which it is defined) as an argument. Functions on numbers that are defined by a rule can usually be expressed by an equation. A linear function is one that can be defined by a linear equation.
if a certain abscissa corresponds to more than one ordinate, then it is not a function.
