Slopes of parallel and perpendicular lines
Slopes of parallel and perpendicular lines
What you'll learn
- Identify parallel lines on a coordinate plane by recognizing that they have equal slopes.
- Calculate the slope of a line given its equation in slope-intercept form (y = mx + b) and use this to determine if it is parallel to another given line.
- Determine if two lines are perpendicular by verifying that the product of their slopes is -1.
- Explain the relationship between the slopes of parallel and perpendicular lines using geometric reasoning.
- Solve problems involving finding the equation of a line that is parallel or perpendicular to a given line and passes through a specific point.
