Mathematics Within: Slope and Triangles
Learners discover a method for determining the slope of a line by creating and comparing similar triangles. They fold coordinate grids to make three similar triangles then measure the sides to compare the relationships between the triangles.

Find the Change
This exercise is an opportunity for algebra learners to understand the connection between the slope of a line and points found on the line. Use similar triangles to explain why slope m is the same between any two points. Discuss with the class the concept that if the y intercept changes, there is a proportional relationship between the line graphs.

Slope and Rate of Change
Introducing slope as "a way of measuring the inclination of a line," Sal endeavors to provide a working knowledge of slope problems and problem solving. The video is framed as a review, but could be a good way to fill any holes in mathematical knowledge.

Slope of a Line 2
Here is the second video in a three-part series on determining the slope of a line. This presentation focuses on defining mathematical terminology and the step-by-step process needed to find the slope the goes through the ordered pairs (4, 2) and (-3, 16).

Line of Best Fit
The cost of chips is going up, while the percentage of voters is going down. Your learners will be able to predict different outcomes when creating a graph with a line of best fit. Using a graphing calculator or not, they can create the line from the data and then use that slope to predict future results.

What is the Slope of the Stairs in Front of the School?
Mathematicians apply the formula for line slope to determine the slope of stairs in their school. They work in small groups to take the appropriate measurements, perform the necessary calculations, and find the mean of their group slope calculations.

Measuring Slope for Rain Gardens
The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a garden or using the entire unit, this lesson can be easily used in any earth science class during the erosion unit.

How Do You Find the Slope of a Line from a Graph?
Given a line on a graph, what's the slope of this line? First, identify two points on the given line. Then, use a formula to find the change in y and then the change in x. This will be represented by rise over run. Watch this video to see how to solve this problem.

Finding Slope of a Line from Graphs, Tables, and Ordered Pairs
Middle schoolers explore the concept of slope in numerous ways and start to look at simple linear equations. They describe the slope in a variety of ways such as the steepness of a line, developing a ratio, using graphs, using similar triangles, and through ordered pairs.

Equations of Parallel And Perpendicular Lines
Drawing a "parallel" to his previous algebra videos, Sal first discusses the main topic of the video - parallel and perpendicular lines - and then works through various equations in the second half of the presentation. Those who have a hard time translating graphs to equations, and vice versa, will enjoy the simplicity and easy instruction in this lesson.

Linear Equations in Point Slope Form
Bridging the knowledge gap between slope-intercept form and point-slope form, Sal explains that the forms are "just two different ways of writing the same equation." This piece of information will be useful to those who have a difficult time deciphering the different types of equations in algebra.

Linear Equations in Slope Intercept Form
Several examples of equations in slope-intercept form are the focus of this video. Instructors who are reviewing slopes and functions with their math classes, or who are introducing the concept for the first time, will appreciate Sal's patient instruction and thorough explanations.

Parallel Lines 3
Starting with three linear equations, how can you tell which lines are parallel? The first equation is rewritten in slope-intercept form. The second equation represents a horizontal line, so it is already in slope-intercept form. The third equation is rewritten in slope-intercept form to verify that the slope was easily determined from the original form.

Here is fairly basic video that takes three equations, each written in slope-intercept form, with the goal of determining whether the lines are parallel. Sal graphs each of the equations on the same coordinate plane to show how their slopes compare.

Point-Slope and Standard Form
Given two points on a line, this video shows how to write the linear equation in point-slope form, slope-intercept form, and standard form. First, Sal reviews each of these forms, then calculates the slope, writes the equation in point-slope form, and finally converts the equation into the other two forms.
