In this video, we create an equation and graph to show a linear relationship based on the word problem. This is a good example for algebra and pre-algebra learners to help them understand creating equations and graphing relationships...

Y equals graphs are horizontal, but x equals graphs are vertical. Learners explore the connection between the graph and the equation of vertical lines while watching an instructional video. The presenter shows a set of ordered pairs...

How can your class determine the relationship between experimental data? Learners discover how to express direct and inverse relationships through examples and sample problems in a video. The narrator takes data from tabular to graphical...

Sal takes your class’s newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems that mathematicians must understand to use linear function graphs.

Slope-intercept form is key to understanding linear relationships. Learners explore the relationship between the equation, graph, and key features of linear functions as they view a video lesson. They then complete practice problems to...

Analyze patterns in equations of parallel lines. Building on previous knowledge of parallel lines and writing linear equations, learners watch how to create an equation of a line parallel to a given line. The video emphasizes the...

Introduce learners to independent and dependent variables with an informative video.The two variables are defined via inputs and outputs. It makes clear that the independent variable is the one that the person has control over,...

With math all around us, your learners will see they can create an equation to model different situations. From fundraising to a cell phone plan, your mathematicians can find the starting point b, plug in the rate of...

Relationships can be good or bad, but functional relationships are the best! The video demonstrates relationships in a table or graph and what makes their qualities functional. Have your learners review functions and then go through a...

Provide the definitions of parallel and perpendicular lines, as well as the relationships between their slopes. Two examples explain the process of finding the equation of either a perpendicular or parallel line to another line through a...

Develop a sequence of descriptions. Learners watch an introduction to sequences, their notations, and how to graph them. Pupils use full sentences to describe the sequence and how to get from one term to the next, without needing to...

Graphs of linear relationships are basically just lines and dots. In this video, you will learn the skills to understand and analyze the graphs to get useful information from them. [1:29]

Linear relationships can help us illustrate real-life relationships such as breakeven points, cost of goods sold to profits, sales to profit, and many more. This video walks you through word problems on linear relationships. [0:41]

This video demonstrates how to solve two different word problems that involve linear relationships. In order to solve the problem an equation must be written and then the video demonstrates how to solve for a particular variable in the...

Explore linear and nonlinear relationships and how to recognize the graphical representations of both. Assess learning with a quiz.

This video demonstrates real-life situations that might result in a linear relationship and shows what this relationship would look like on a graph. It also identifies when x and y values vary directly and when x and y values vary...

This video demonstrates real-life situations that might result in a linear relationship and shows what this relationship would look like on a graph.

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 video teaches how to determine if an expression is a linear equation; and how to graph a linear equation. [1:35]

Watch this video to learn how to use the distance formula to calculate the distance between two points on a graph when you know the coordinates of both points. [1:45]

Presents a problem with two graphs: study time vs. test score and shoe size vs. test score. Discusses the linear and nonlinear relationships that the graphs show. [2:26]
