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.
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. This lesson has an amazing collections of great ideas when it comes to exploring slope.
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). This is a good introduction to the topic.
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.
Constructing Equations in Slope-Intercept Form from Graphs
This lecture continues reviewing linear equations and slope problems with several example problems. Those who didn't grasp the concepts during class might find this lesson helpful.
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.
New! Parallel Lines
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. The video assumes the listener has a basic knowledge of graphing lines in slope-intercept form and what it means for lines to be parallel.
Equation of a tangent line
Using a specific example, Sal shows how to find the equation of a tangent line to a given function at a specific point. Specifically, he solves the problem of finding the tangent line to the function f(x) = xex at x = 1. This problem provides a review of the product rule, slope-intercept form of a line, and steps for finding the equation of a line. It also, provides a nice visual understanding of the problem by graphing both the original equation and the found tangent line.
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. The slope equation or rise over run is developed from these relationships.
Calculus: Derivatives 1 (new HD version)
Sal defines the term derivative by taking the listener on a well-organized tour of slope. First, he reviews the concept of slope of a line from algebra, then extends this idea to look at the slope of the curve by first examining a secant line to the curve and then using our knowledge of limits, defining the limit as _x approaches zero to get the slope of the tangent line to the curve. Along with the video, there is an interesting practice module that models the connection between the slopes of the tangent lines and the derivative of a function.
How Do You Find the Slope of a Line from Two Points?
The teacher demonstrates how to plug in values from two given points to find the slope of a line. She uses the slope formula and goes through the problem step-by-step.
Stars and Slopes
More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive. Use it in your calculus or physics curriculum.
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.
Learners identify the slope of linear functions. In this slope instructional activity, students collect data and graph it. They write equations with no more than two variables and use technology to explain their data.
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.
Parallel Line Equation
Present this practice problem to assist your class in determining how to write an equation of a line that is parallel to the given equation and travels through the provided point. Young mathematicians will need to have an existing understanding of slope intercept and algebraic graphing to maximize this video's benefit.
Analyzing Equations Through Slope and Y-int
With problems applying to modern-day topics like Netflix and McDonald's, math whizzes analyze graphs and investigate the slopes. For this algebra worksheet, learners identify the slope and y-intercept of the given equations. They graph lines using the slope-intercept form, y=mx+b.
Equation of a line 3
Use ordered pairs to graph a line and determine its equation. This practice problem houses a short lesson clearly demonstrating how to use ordered pairs and the slope intercept form to determine the related equation.
Graphical Slope of a Line
Algebra students follow along as Sal determines the line's slope. He reminds students that slope=rise/run, and what that means on a graph in relation to the line given. Background information is recommended prior to viewing this video.
Fitting a Line to Data
Sal trades his tablet for an Excel spreadsheet in this video, which covers fitting data to a line. Using a word problem about median income, he not only solves the problem but demonstrates how to successfully use scatter plots and Excel tools in math problems.
