Sophia: Solving Linear Inequalities by Graphing

Your learners will appreciate the complete picture of linear inequalities presented in this lesson plan. Starting simply with definitions and moving all the way to solving linear inequality word problems this activity is simple to...

In this interval notation and linear inequalities activity, students use number lines and solve equations. Students complete 64 problems total.

Life isn't fair ... like inequalities. After first reviewing inequality symbols and how to read inequality statements, learners discover how to solve one-step inequalities and graph their solution sets.

Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Another method for solving systems of equations, other than graphing, is the focus in this video as Sal demonstrates substitution. It's important to understand that there is more than one way to solve any problem, especially if one has a...

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.

The student will represent linear inequalities using equations, tables, and graphs. The student will solve linear inequalities using graphs or properties of equality, and determine whether or not a given point is a solution to a linear...

Twenty-six problems present a variety of practice solving linear inequalities. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View Solution" button to...

Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.
