The Slope of a Line: Finding the Slope of a Line from a Graph How to Draw a Line with a Given Slope through a Given Point (03:43) 
Summary of the Properties of Slope
Properties of Linear Graphs (07:19) 
Parallel Lines and Angles (13:00) 
PARALLEL AND PERPENDICULAR LINES
In this unit, you will examine the relationships of parallel and perpendicular lines. You will begin with taking a close look at the slopes of lines, and then compare the slopes of parallel and perpendicular lines. You will construct angles, parallel lines, and perpendicular lines. Finally, you will define the distance between parallel lines and apply the distance formula to parallel and perpendicular lines in a coordinate plane.
