In this lesson, we learn about linear equations in two variables, and how any ordered pair that makes the equation true is a solution. We go through examples of finding ordered pairs that satisfy the equation, and then graphing these ordered pairs on a graph to represent all the solutions to the equation. We also learn how to determine if a given ordered pair is a solution to an equation, which is useful for checking our work when graphing the solutions.
Covers how to determine is a given ordered pair is a solution to an equation and therefore a point on the line. Also shows how to find ordered pair solutions to a linear equation. This is part 2 of a series of videos about graphing lines.
