Khan Academy: Algebra I: Linear Equations: Absolute Value Equation Example 2

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...

Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.

Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.

This video demonstrates how to write a linear equation in point-slope form, slope-intercept form, and standard form given two points on the line. [7:56]

This video demonstrates how to solve systems of linear equations in two variables using the elimination method. There are three sample problems shown. [9:57]

Watch [3:21] Sal work through a harder systems of linear equations word problems.

Given a table with values of two quantities over time, determine whether the quantities grow linearly or exponentially. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive...

Solve word problems about real world relationships that are given in formulas. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The sole purpose of this interactive is to graph a function representing the distance of a car from a shoe store. Scholars use an interactive to graph such an absolute value function. They then answer a set of challenge questions...

Given the x or y value of a 2-variable equation solution, find the value for the other variable in the solution. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
