# Unit 4 Linear Equations Homework 13 Answer Key

Linear equations are an essential part of mathematics and understanding them is essential for success in many areas of life. Having the right answer key to linear equation homework can make the difference between success and failure in a math class. Here we will discuss the answer key to homework 13 of unit 4 linear equations.

## What is linear equation?

A linear equation is an equation that involves a single variable and can be written in the form of a straight line. For example, the equation y = 2x + 7 is a linear equation. The equation describes a line with a slope of two and a y-intercept of seven. Linear equations can be used to solve a variety of problems, from calculating the area of a triangle to determining the speed of an object.

## How to solve linear equation?

There are several strategies for solving linear equations. The most common method is to use the “elimination” method, which involves multiplying one side of the equation by a constant and then subtracting the result from both sides. This is usually the fastest way to solve linear equations. Another method is to use the “substitution” method, which involves replacing one of the variables with its value and solving for the other variable. This method is often the easiest way to solve linear equations.

## Answer Key for Unit 4 Linear Equations Homework 13

The answer key for unit 4 linear equations homework 13 is as follows: y = 2/3x + 4. This equation describes a line with a slope of two-thirds and a y-intercept of four. To solve this equation, we can use either the elimination or substitution method. To use the elimination method, we can multiply one side of the equation by three and then subtract the result from both sides. This will yield the answer of y = 2/3x + 4.
