Background Tutorials
Introduction to linear equations.
How Do You Make a Table of Values for a Linear Equation?
To graph a linear equation, you could make a table of values to plot, but first you'll need to know how to make the table. Take a look at this tutorial! You'll see how to set up a table, choose appropriate x-values, plug those values into the equation, and simplify to get the respective y-values. This tutorial shows you how to set up a table of values for a linear equation!
What is a Linear Equation?
If you're learning about graphs, you're bound to see a bunch of linear equations, so it's a good idea to understand what makes an equation a linear equation. This tutorial explains linear equations and shows you the difference between equations that are linear and ones that are not. Check it out!
Evaluating Expressions
What is a Variable?
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
Ordered Pairs and The Coordinate Plane
How Do You Plot Points in the Coordinate Plane?
Knowing how to plot ordered pairs is an essential part of graphing functions. In this tutorial, you'll see how to take an ordered pair and plot it on the coordinate plane. Take a look!
What is an Ordered Pair?
Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!
What is the X-Axis?
To graph a function or plot an ordered pair, you need to use a coordinate plane, so you should learn all about it! In this tutorial, you'll learn about the x-axis and see where it's located in the coordinate plane.
What is the Y-Axis?
To graph a function or plot an ordered pair, you need to use a coordinate plane, so you should learn all about it! In thi
Further Exploration
Exponential functions.
How Do You Graph an Exponential Function Using a Table?
Graphing an exponential function? No sweat! Create a table of values to give you ordered pairs. Then, plot those ordered pair on a coordinate plane and connect the points to make your graph! Follow along with this tutorial as it shows you all the steps.
