A linear function is a fundamental mathematical function that describes a straight-line relationship between two variables, typically denoted as ‘x’ and ‘y’.
It can be expressed in the form y = mx + b, where ‘m’ represents the slope of the line (rate of change) and ‘b’ is the y-intercept (the point where the line crosses the y-axis).
Linear functions are characterized by a constant rate of change and produce a straight line when graphed.
They are widely used in various fields to model and analyze relationships with a linear or proportional nature.
