In this chapter, you'll learn the answer to questions including:
- What is the definition of linear equations?
- How can I write linear equations?
- How do I graph linear equations?
- What is the definition of inequality?
- How do I solve simultaneous linear equations?
- How can I extrapolate values and interpolate data using line graphs?
1. Extrapolation & Interpolation with Line Graphs
After watching this video lesson, you should be able to interpolate and extrapolate a line graph based on just a few points. You will be able to provide data points that haven't been given to you.
2. How to Write a Linear Equation
Simply knowing how to take a linear equation and graph it is only half of the battle. You should also be able to come up with the equation if you're given the right information.
3. Linear Equations: Intercepts, Standard Form and Graphing
Do you know what to do if an equation doesn't look like y=mx+b?! If not, then this video is for you. Chances are the equation is in standard form, so we'll learn how to use standard form equations, how to graph them and why they can be helpful.
4. Solving Simultaneous Linear Equations
In this video lesson, you will learn how to solve simultaneous linear equations or a system of linear equations. Learn the steps you need to take to solve any such system using the Gaussian elimination method.
5. What is a Linear Equation?
Most cars won't be able to run for more than 250,000 miles, so how much longer will your car live? Linear Equations are the most basic kind of algebraic function and can help you answer questions exactly like this. Learn about what they look like, how they come up in your life and why they are powerful tools.
6. What is an Inequality?
Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!
7. How to Solve Linear Functions
Solving linear functions is a common and important part of mathematics. In this lesson, you will find step by step instructions for solving linear functions. You will also see how to check your work and see examples of alternate versions of linear function solutions.
