Interval Notation and Linear Inequalities

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

Add more points on the graph ... and it still remains a line! The 13th installment in a series of 33 leads the class to the understanding that the graph of linear equation is a line. Pupils find several solutions to a two-variable linear...

In this interval notation worksheet, students solve inequalities, sketch a graph of the answer, and write the answer using interval notation. This one-page worksheet contains 8 problems, with answers.

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...

It's a step in the right direction! A video lesson demonstrates how to solve one-step linear equations. The instructor explains each step and shows the work, including how to check answers.

Solving two-step equations is twice as fun as one-step equations! A thorough lesson shows the steps to solving two-step equations. Learners watch as the instructor not only explains how to use each operation but also explains why the...

Time to do a little two-step! Young scholars view a lesson on solving two-step equations. The video instructor shows several examples that include all different operations. The instruction emphasizes using the properties of equality as a...

Inverse operations are the key! A thorough instructional lesson describes the steps to solve one-step equations. The video instructor outlines how to use inverse operations to solve the linear equations.

Solving equations is as easy as 1-2-3. Using two examples, the video shows the order of the steps to use when solving a two-step equation. It uses a vertical approach to perform the inverse operations to isolate the variable. To finish,...

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