#### 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...

Lesson Planet

#### 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...

Lesson Planet

#### Graphing a Line in Slope Intercept Form

In this short video, Sal shows how to graph a line in slope-intercept form.

Lesson Planet

#### Converting to slope-intercept form

This video shows how to graph a linear equation in standard form. He shows three different examples where he changes each equation into slope-intercept form and graphs it. One of the examples is a line with a negative slope, one is a...

Lesson Planet

#### Algebra: Linear Equations 4

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.

Lesson Planet

#### Algebra: Equation of a Line

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, put these values into the equation of a line y =...

Lesson Planet

#### Parallel Lines 2

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.

Lesson Planet

#### 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...

Lesson Planet

#### Diapers

Most of your students probably think a car or college is the first big expense their parents could help them with, but as it turns out these kids have been costing their parents for their whole lives. Have they ever considered how much...

Lesson Planet

#### Going to the Game (systems)

Seven real-life math problems require the solving of simultaneous pairs of linear equations. Although a similar approach is taken for most of the problems, the topic of sports stadium concessions should keep the interest level high. As a...

Lesson Planet

#### Solving Linear Equations in One Variable

A thorough and professional appearance characterizes a instructional activity on linear equations. Maturing mathematicians are taught to identify and exemplify linear equations with a single variable. They also classify equations...

Lesson Planet

#### Graphs of Linear Equations

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 word problems that are more complicated.

Lesson Planet

#### 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.

Lesson Planet

#### Linear Equations in Standard Form

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...

Lesson Planet

#### SAT Prep: Test 2 Section 3 Part 1

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.

Lesson Planet

#### SAT Prep: Test 1 Section 9 Part 3

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...

Lesson Planet

#### SAT Prep: Test 1 Section 9 Part 2

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...

Lesson Planet

#### SAT Prep: Test 3 Section 8 Part 1

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...

Lesson Planet

#### SAT Prep: Test 3 Section 4 Part 4

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...

Lesson Planet

#### SAT Prep: Test 1 Section 9 Part 1

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...

Lesson Planet

#### 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...

Lesson Planet

#### SAT Prep: Test 3 Section 4 Part 1

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...
