Learners construct and use inverse functions to model a real-world context. They use the inverse function to interpolate a data point.

Your learners can approach this task algebraically, geometrically, or both. They analyze the building of a linear function given two points and expand the concrete approach to the abstract when they are asked to find the general form of...

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.

Beginning a series based on The Official SAT Study Guide(first edition), the speaker (Sal) deftly demonstrates how to work through the types of problems typically seen on the SAT. He assumes that the reader is also working from the...

Watch this video to learn how to find the solution to a system of equations with the substitution method! A teacher will lead you through each step necessary, explaining her steps and the reasoning behind her decisions. After watching...

Since the focus of this video is on explaining the solution to a system of equations, the lecturer does not work through the problem. Instead, she points out that the solution should be an ordered pair that makes each equation a true...

Ever have a math teacher that gives you a property or rule but doesn't give you any way to remember it? Well he just made a math tutorial. This video does provide examples and shows the addition and multiplication property of equations...

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.

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

In this linear equations worksheet, students solve 36 linear equations. Students write equations of lines in slope intercept form given a graph, standard form, two points, and slope and a point.

In this linear equations activity, students solve linear equations for the variables with negatives and fractions. Students complete 28 problems.

How can you graph lines that don't seem to fit on the given graph? What makes a line straight? What does the rate of change mean when graphing a line? How do you know if a slope is positive or negative? How do you know if the graph of a...

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.

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.

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...

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...
