## What is linear function and examples?

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

## What defines a linear function?

1 : a mathematical function in which the variables appear only in the first degree, are multiplied by constants, and are combined only by addition and subtraction.

Start by finding the slope. So this will be X sub 1 and Y sub 1. This will be X sub 2 and Y sub. 2.MoreStart by finding the slope. So this will be X sub 1 and Y sub 1. This will be X sub 2 and Y sub. 2. So the slope of our line will be y sub 2 minus y sub 1 divided by X sub 2 minus X sub 1.

## What does linear function look like?

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

## How do you write a linear function f?

A linear function is a function of the form f(x) = ax + b, where a and b are real numbers. Here, a represents the gradient of the line, and b represents the y-axis intercept (which is sometimes called the vertical intercept).
