Slope of Parallel and Perpendicular Lines Explained

This video tutorial explores the relationship between parallel and perpendicular lines on a coordinate grid. It explains that parallel lines have the same slope, while perpendicular lines have opposite reciprocal slopes. The video demonstrates how to find the slope of lines parallel or perpendicular to a given line by converting equations into slope-intercept form. Key properties of these lines are highlighted, such as parallel lines never intersecting and perpendicular lines meeting at right angles.

What is a common characteristic of parallel lines?

• They have opposite slopes

• They intersect at a right angle

• They never intersect

• They have the same slope
