A linear equation in two variables is of the form: ax + by = c. We previously learned how to find ordered pair solutions. We can plot those ordered pairs on a coordinate plane. We then sketch a line through the points to visually display the solution set. We place arrows at each end of the line to indicate the line continues forever in each direction.
Test Objectives:•Demonstrate the ability to create a table of ordered pairs
•Demonstrate the ability to plot ordered pairs on a coordinate plane
