Linear Function
f(x)=x
A linear function is a mathematical function that has a constant rate of change. In other words, the graph of a linear function is a straight line, and the change in the function’s output is proportional to the change in its input. The general form of a linear function is y = mx + b, where m is the slope of the line (the rate of change of y with respect to x) and b is the y-intercept (the point where the line intersects the y-axis).
For example, the equation y = 2x + 3 represents a linear function with a slope of 2 and a y-intercept of 3. This means that for every increase of 1 in the input variable x, the output variable y will increase by 2. The graph of this linear function is a straight line that passes through the point (0,3) and has a slope of 2.
Linear functions are commonly used in many fields of study, such as economics, physics, and engineering, to model relationships between variables that have a constant rate of change. They are also used in algebra as a basic concept in the study of systems of linear equations and matrices.
