Solving Inequalities and Graphing

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Graphing all kinds of situations in one and two variables is the focus of this detailed unit of daily lessons, teaching notes, and assessments. Learners start with piece-wise functions and work their way through setting up and solving...

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...

The teacher shows how draw a number line and graph an inequality using an open circle. She also shows how to graph a set of numbers on a number line.

Is the boundary line part of the graph of an inequality? Here's a hint: the sign of the inequality holds the answer! Are the brain cells firing up trying to figure out what that means? Watch this video as the instructor graphs the...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or dividing by...

The concept of absolute value can be difficult for learners to grasp. Reinforce their understanding of a basic absolute value expression and connect it to solving equations and inequalities. Scholars write two equations/inequalities to...

Do you know how to graph a linear equation? If you do then graphing an inequality will not be a problem for you. There are a couple of differences: is the line solid or dashed, and which half plane do you have to shade. Watch this video...
