Parallel and Perpendicular Lines Objectives: Define parallel and perpendicular lines Find Equations of parallel and perpendicular lines
Slopes of Parallel and Perpendicular Lines • Parallel Lines have the same slope • Perpendicular Lines have the opposite reciprocal slopes or the product of the slopes equals –1 • EX: Find the slope of the lines parallel and perpendicular to the given lines.
Find the Equation of the line • 1. Through and parallel to • 2. Through and perpendicular to
Find the Equation of the line • 3. Through and parallel to x-axis • 4. Through and parallel to y-axis
Find the Equation of the line • 5. Through the y-int. = 4 and perpendicular to • 6. Through and perpendicular to
