This video shows how to graph a linear equation in standard form. He shows three examples of changing each equation into slope-intercept form and graphing it. One example is a line with a negative slope, one is a vertical line, and the...

This is a lesson in solving linear equations. More specifically, students will see how to solve an equation with a variable expression in the denominator of a fraction.

Given two points on a line, find the value for slope using the rise over run formula. Then, find the y-intercept by plugging one of the point values into the equation of a line. Finally, these values are put into the equation of a line y...

Can you tell, algebraically, if three lines are parallel? In this video, Sal demonstrates how to rewrite linear equations in slope-intercept form and compare the slope of each 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...

This video examines a simple rate problem. The listener must compute whether four trains traveling different distances over different amounts of time are moving at the same constant rate. This problem reinforces one's basic understanding...

Variables on both sides of the equation are the name of the game in this video, and Sal's easygoing manner and thorough instructions make even complicated algebraic equations look like games. He warms up with two equations to demonstrate...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.

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.

Illuminate the world of mathematics for your class, specifically, the process of linear equations. In this video, Sal teaches about linear equations in standard form after two videos on slope-intercept and slope-point forms. He defines...

Page 459 of The Official SAT Study Guide by The College Board features another set of practice SAT math problems, beginning with problems 1-4. Sal demonstrates how to solve problems with factoring and visualization.

If it takes a long time to complete the problems on the math SAT, it doesn't matter if they are correct - the problems that are left over will count against the student's score. Sal takes care to show quicker ways to complete problems...

On problems 5-8 of the practice SAT video series (page 424 of The Official SAT Study Guide), Sal demonstrates several different ways to solve each problem in an efficient and timely manner. Students will appreciate the ways he details...

Section 8 of the practice tests from The Official SAT Study Guide begins with problems about sets of integers, linear equations with radicals, and geometric angles, among others. Sal solves each problem in quick succession, demonstrating...

Adding the values of angles, deciphering fraction word problems, and solving complex linear equations are all in a day's work for Sal, who will stop at nothing to help your students pass the SAT. His clear annotations and strong...

With a brand new review session, Sal addresses common skills required to take - and pass - the SAT. He uses problems 1-4 on page 423 of The Official SAT Study Guide to demonstrate solving problems with linear equations, ratios, and...

Bridging the knowledge gap between slope-intercept and point-slope forms, Sal explains that the forms are "just two different ways of writing the same equation." This information will be useful to those who have difficulty deciphering...

Modeling quick thinking and efficient problem solving, Sal works through the linear equation in problem 1 in just over 30 seconds. This video, which covers problems 1-5 on page 530 of The Official SAT Study Guide, also shows students how...

Helping students realize the common missteps in solving the average SAT problem, Sal creates a lens through which students can clearly see the correct and incorrect approach to each type of problem. He points out what a student might...

Sal's dedication is clear in this video, which takes place on Thanksgiving Day. The problems focus on algebra (averages and linear equations) and geometry (perimeters and angles). Viewers beware: Sal makes a self-professed error on...

The next section of the practice SAT from The Official SAT Study Guide (page 594) covers simple linear equations and geometric figures. Students will appreciate Sal's quick problem solving and thought process, which is easy to understand...

Test eight from The Official SAT Study Guide includes eighteen problems, the first four of which are featured in this video. Basic algebraic expressions, linear equations, tangent circles, and coordinates on a plane test algebra and...

A new set of SAT practice questions from the Official SAT Study Guide (page 803) greets Sal and the viewer. Problems 1-7 involve basic algebraic equations, linear equations, and geometric figures.

Sal is having a blast in this video, and his fun-loving attitude will rub off on even your most stressed-out test-takers. Problems 7-10 in the practice SAT require skills in linear equations, as well as approximation and basic algebra.
