## Parallel and Perpendicualr Lines

Now, you will build on your knowledge of writing equations of linear functions, drawing their graphs, and performing transformations by exploring parallel and perpendicular lines. You will learn how to identify whether lines are parallel or perpendicular given their equations and graphs. You will also learn how to define the equation of a line parallel or perpendicular to another line given an equation and a point.
