A linear function refers to when the dependent variable (usually expressed by 'y') changes by a constant amount as the independent variable (usually 'x') also changes by a constant amount. For example, the number of times the second hand on a clock ticks over time, is a linear function.

A linear function is an algebraic equation, in which each term is either a constant or the product of a constant and a variable (raised to the first power). For example, the equation y=ax+by=ax+by=ax+b is a linear function since both variables x and y meet the criteria, and both constants a and bdo as well. The exponent of x is 1, that is, it is ra...
The origin of the name “linear” comes from the fact that the set of solutions of this type of function forms a straight line in the Cartesian plane. On the graph of a linear function f(x)=mx+bf(x)=mx+bf(x)=mx+b, m determines the slope of that line, that is, the steepness, and b determines the y-intercept, that is, the point where the line crosses t...
A linear function creates a straight line when graphed on the Cartesian plane. Therefore, if it is possible to graph the function, you can easily determine if a function is linear by checking that its graph produces a straight line. To know if a function is linear without having to graph it, we need to check if the function has the characteristics ...

You know that a linear function satisfies the following property: $$f(a+b)=f(a)+f(b)$$ and you want to determine whether a particular function $g$ is linear, so you just check whether this property holds.
Linear functions can be written in the slope-intercept form of a line. f (x)=mx+bf (x)=mx+b. where bb is the initial or starting value of the function (when input, x=0x=0 ), and mm is the constant rate of change, or slope of the function. The y -intercept is at (0,b). (0,b).
21 de nov. de 2023 · The easiest way to know if a function is linear or not is to look at its graph. A linear function forms a straight line when it is plotted on a graph. A nonlinear function does not form...
A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y-intercept is at (0, b).
