Graphing Inequalities in One Variable

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

A different way to look at integers is on this number line with variables in place of numbers. Learners are to look at different expressions and describe why they think the answer would be positive or negative, depending on the location...

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...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

The instructor demonstrates how to read a number line graph to write an inequality. There are several steps involved which are explained clearly.

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.

Go over how to solve a compound inequality and graph it with this video. The video is clear and concise. A lecturer solves a compound inequality and graphs it on the spot, explaining each operation in detail. Great for in-class or...

Given a linear equation, find the x-intercept and the y-intercept to graph the line. Not sure what to do or where to start? Watch this video and see the instructor break it down and make it understandable.

Parallel lines must always have the same slope. Learners use this bit of information to extend their equation writing skills. A video lesson explains how to write the equation of a line parallel to a given line and through a given point....
