What is a Linear Equation?

1. What is a Linear Equation?

A linear equation is a pattern of numbers with proportional increase or decrease that is used to represent a line graph. Learn how to plot a graph and build and solve a linear equation.

Linear Equations: Intercepts, Standard Form and Graphing

2. Linear Equations: Intercepts, Standard Form and Graphing

To solve a linear equation, begin by determining whether it is written in the standard form or the slope-intercept form. Explore the differences between the slope-intercept form and the standard form of a linear equation, and learn how to graph the point of intercept for each.

Evaluating Simple Algebraic Expressions

3. Evaluating Simple Algebraic Expressions

To evaluate simple algebraic expressions, substitute a number for each variable and solve. Learn the steps for evaluating simple algebraic expressions, including rules for order of operations and parentheses, and tackle the practice problems in this lesson.

Writing Equivalent Expressions: Definition & Examples

4. Writing Equivalent Expressions: Definition & Examples

In mathematics, algebraic expressions are composed of any combination of variables, numbers, exponents, and operations. Learn about algebraic expressions, and explore the process for writing equivalent expressions. Review the definitions and key terms, beware non equivalence, and consider examples to ensure understanding.

Solving Linear Equations: Practice Problems

5. Solving Linear Equations: Practice Problems

Linear equations are algebraic expressions of a line. Become familiar with recognizing and solving linear equations through examples and practice problems.

Solving One-Step Linear Inequalities

6. Solving One-Step Linear Inequalities

One-step linear inequalities are expressed with inequality signs (< or >) instead of equal signs (=) and can be solved in different ways. Learn how addition, subtraction, multiplication, and division are all useful tools to solve these equations.

How to Solve One-Step Algebra Equations in Word Problems

7. How to Solve One-Step Algebra Equations in Word Problems

Certain word problems can be translated into an algebraic equation and solved in a single step. Learn the definition of a one-step algebra equation, and understand how to translate the practice word problem into an equation and solve in it one step.

Abstract Algebraic Examples and Going from a Graph to a Rule

8. Abstract Algebraic Examples and Going from a Graph to a Rule

Abstract algebraic concepts are often difficult to understand because they do not include many numbers but are mostly variables and letters. Learn more about abstract algebraic concepts, finding the equation on a graph, identifying graphs by appearance, and finding the greatest slope on a graph.
