Linear Equations: Introduction

A linear equation is an algebraic equation in which each term has an exponent of 1 and when plotted, it forms a straight line. It is often written in the form y = mx + b, where m is the slope of the line and b is the y-intercept. Understanding linear equations is fundamental to many areas of mathematics and science.

For example, if you are tracking the distance traveled by a car moving at a constant speed, you can use a linear equation. The distance (y) would be equal to the speed (m) multiplied by the time (x), plus any initial distance (b).
