The coordinate axes are the x-axis, which is the horizontal axis, and the y-axis, which is the vertical axis. Remember, these axes go on forever.

A simple video on how to identify the endpoints of a line segment. Have your class watch this video to clarify any confusions about endpoints. This could be used as extra help for learners who are having difficulty, or as a supplement to...

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

One way to get values to be able to graph an exponential function is to make a table. This seems pretty straightforward. Set up a table to plug in random values for x. Then put those values into the equation to get the y-values. These...

Since the focus of this video is on explaining the solution to a system of equations, the lecturer does not work through the problem. Instead, she points out that the solution should be an ordered pair that makes each equation a true...

The teacher illustrates several ways to look at what the range is in a set of numbers. Input, output, stem and plot table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of range.

The coordinate axes are the x-axis, which is the horizontal axis, and the y-axis, which is the vertical axis. Remember, these axes go on forever.

In Algebra 1 the concept of relations is studied. As a starting point to this unit, guide your learners to identify algebraic relations and discriminate the domain and range within an ordered pair though this informative video. Assign...

A linear equation is an equation whose graph is a line. Watch this video for an in-depth explanation and examples of both linear and non-linear equations. [5:48]

This QuickTime movie provides an explanation of Truth Tables, ordered pairs, and graphing the ordered pairs. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this concept.

This video provides an opportunity to identify a number pattern. Then organize that data in a data table and graph it. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this...

This tutorial illustrates how to draw a line of fit on a scatter plot and find the equation of that line in order to make a prediction based on the data already given. [6:47]

This tutorial helps explain linear equations and shows the difference between equations that are linear and ones that are not. [5:48]

Video tutorial demonstrates how to graph ordered pairs on a coordinate plane. [2:20]

Video tutorial explores how to determine if a relation given by a set of ordered pairs is a function. [6:56]

This tutorial takes a look at relations which are a set of ordered pairs. [0:50]

This tutorial introduces ordered pairs and shows why they are a fundamental part of graphing. [2:20]

When an equation has two variables, the set of ordered pairs that are the solution to the equation is called the solution set to the equation. In this tutorial, you'll learn the definition of a solution set and see an example. [0:59]

With a given slope, determine the coordinate of an order pair that falls on a line. Assess learning with a quiz.
