Linear Functions

Linear functions are a fundamental concept in mathematics that describe a straight line. They are used to model a wide variety of real-world phenomena, from the motion of objects to the growth of populations. Linear functions are relatively simple to understand and use, making them a valuable tool for students, researchers, and professionals in many different fields.

What is a Linear Function?

A linear function is an equation that represents a straight line on a graph. The equation of a linear function is typically written in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). The slope of a line tells you how steep it is, and the y-intercept tells you where the line crosses the y-axis.
