Lesson Summary:

In this video, you will learn how to find ordered pair solutions to equations by plugging in values for x or y. You will also learn how to create a table of ordered pairs and graph the line through those pairs to find all the solutions to the equation. By the end of the lesson, you will understand how to find three ordered pairs for any linear equation and how to double-check your work to ensure the correctness of your solution.

Lesson Description:

Covers how to complete ordered pair solutions if the x or y coordinate is given. Also covers how to make a table of ordered pair solutions if the equation is solved for y, how to plot those on the x-y plane and graph the line. This is part 3 of a series of videos about graphing lines.

    This video explains how to find an unknown value of a variable in an equation given the value of the other variable. This allows you to find ordered pair solutions to an equation so you can plot them and graph the solution set of the equation on a coordinate plane.

    I'm a homeschooling mom and this was such a lifesaver for my daughter and I. We are both learning!
