in this lesson our instructor talks about definition of slope and slope equation. She teaches how to find the slope of a line and proving the slope postulates. She then discusses the parallel and perpendicular lines. She also talks about using the slope formula. Four extra example videos round up this lesson.
Slope = the ratio between the vertical rise and horizontal run
The slope m of a line containing two points with coordinates (x1, y1) and (x2, y2) is given by the formula
Two non-vertical lines have the same slope if and only if they are parallel
Two non-vertical lines are perpendicular if and only if the product of their slopes is -1
