Linear refers to a type of function or equation that represents a straight line graphically. It can also describe a relationship or pattern that follows a straight line.

In mathematics, a linear equation is an equation in which the variables are raised to the power 1. These equations can be written in the form: y = mx + b, where m and b are constants. The coefficient ‘m’ represents the slope of the line, and ‘b’ represents the y-intercept, which is the point where the line intersects with the y-axis.

Linear functions are characterized by constant rates of change. This means that as the input value (x) increases or decreases by a constant amount, the output value (y) also changes by a constant amount. The graph of a linear function is a straight line, and any two points on the line can be used to determine its slope.

Linear equations and functions have numerous applications in various fields of mathematics and also in real-life situations. They can be used to represent relationships in physics, economics, engineering, and many other disciplines. Additionally, linear regression, a statistical technique, involves fitting a straight line to a set of data points in order to model and make predictions based on the data.

In summary, the term “linear” in mathematics refers to equations, functions, or relationships that exhibit a constant rate of change and can be graphically represented by a straight line.
